Solveby factoring :
p2 + 8p + 12 = 0
(show steps please)
Answer:
(p + 6)(p + 2)
Step-by-step explanation:
I believe you meant p^2 + 8p + 12 = 0, in which " ^ " indicates exponentiation.
Note that 12 = 2*6, and that these two factors, 2 and 6, add up to 8. Thus,
p^2 + 8p + 12 = 0 = (p + 6)(p + 2)

Answer:

[tex]\:\left(\frac{\left(x^2y^3\right)^{-1}}{\left(x^{-2}y^2z\right)^2}\right)^2=x^4y^{-14}z^{-4}[/tex]
The exponent on x is 4The exponent on y is -14The exponent on z is -4Step-by-step explanation:
Given the expression
[tex]\left[\frac{\left(x^2y^3\right)^{-1}}{\left(x^{-2}y^2z\right)^2}\right]^2[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]
[tex]\left(\frac{\left(x^2y^3\right)^{-1}}{\left(x^{-2}y^2z\right)^2}\right)^2=\frac{\left(\left(x^2y^3\right)^{-1}\right)^2}{\left(\left(x^{-2}y^2z\right)^2\right)^2}[/tex]
[tex]=\frac{\left(\left(x^2y^3\right)^{-1}\right)^2}{\left(\left(x^{-2}y^2z\right)^2\right)^2}[/tex]
as
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-1}=\frac{1}{a}[/tex]
so the expression becomes
[tex]=\frac{\frac{1}{x^4y^6}}{\left(\left(x^{-2}y^2z\right)^2\right)^2}[/tex] ∵ [tex]\left(x^2y^3\right)^{-1}=\frac{1}{x^2y^3}[/tex]
as
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n[/tex]
so the expression becomes
[tex]=\frac{\frac{1}{x^4y^6}}{\frac{y^8z^4}{x^8}}[/tex] ∵ [tex]\left(x^{-2}y^2z\right)^2=\frac{y^4z^2}{x^4}[/tex]
as
[tex]\mathrm{Divide\:fractions}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]
so the expression becomes
[tex]=\frac{1\cdot \:x^8}{x^4y^6y^8z^4}[/tex]
[tex]=\frac{x^8}{x^4y^6y^8z^4}[/tex]
as
[tex]\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}[/tex]
so the expression becomes
[tex]=\frac{x^{8-4}}{y^8y^6z^4}[/tex]
[tex]=\frac{x^4}{y^8y^6z^4}[/tex]
[tex]=\frac{x^4}{y^{14}z^4}[/tex]
as
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-1}=\frac{1}{a}[/tex]
so the expression becomes
[tex]=x^4y^{-14}z^{-4}[/tex]
Therefore,
The exponent on x is 4The exponent on y is -14The exponent on z is -43
Lee has -£13 in his bank account. Every week he gets paid £45, and
spends £60. How much will Lee have in his bank account after 3 weeks?
Answer:
Lee has -£13 in his bank account.
Every week he gets paid £45, and spends £60.
IN 3 WEEKS
He gets paid --> £45 · 3 = £135
He spends money --> £60 · 3 = £180
£135 - £180 = -£45
He had -£13 initially
He now has --> -£13 - £45 = -£58

Step-by-step explanation:
Rounding a number involves replacing the number with an approximation of the number that results in a shorter, simpler, or more explicit representation of said number based on specific rounding definitions. For example, if rounding the number 2.7 to the nearest integer, 2.7 would be rounded to 3.

A ship leaves port on a bearing of 20.2 degrees East of North and travels 6.5 miles. The ship then turns due East and travels 3.8 miles.
How far is the ship from the port, and what is its bearing?
Distance: 8.6 miles; Bearing: 20.2 degrees West of North.
Distance: 8.6 miles; Bearing: 20.2 degrees East of North.
Distance: 8.6 miles; Bearing: 44.7 degrees East of North.
Distance: 8.6 miles; Bearing: 44.7 degrees West of North.
Answer:
C
Step-by-step explanation:
Distance: 8.6 miles; Bearing: 44.7 degrees East of North.
The distance of the ship which leaves port on a bearing of 20.2 degrees East of North is 8.6 miles and its bearing is 44.7 degrees East of North.
What is cosine law?When the three sides of a triangle is known, then to find any angle, the law of cosine is used.
It can be given as,
[tex]c^2=a^2+b^2-2ab\cos C\\a^2=c^2+b^2-2ab\cos A\\b^2=a^2+c^2-2ab\cos B[/tex]
Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.
A ship leaves port on a bearing of 20.2 degrees East of North and travels 6.5 miles. The ship then turns due East and travels 3.8 miles.
This problem is shown in the image. The distance of ship from initial point is,
[tex]c=\sqrt{6.5^2+3.8^2-{2\times6.5\times3.8\times\cos (110.2)}}\\c\approx8.6\rm\; miles[/tex]
The measure of the angle x is,
[tex]\angle x=\cos^{-1}\dfrac{8.6^2+3.8^2-6.5^2}{2\times8.6\times3.8}\\\angle x=44.7^o[/tex]
Hence, the distance of the ship which leaves port on a bearing of 20.2 degrees East of North is 8.6 miles and its bearing is 44.7 degrees East of North.

7) How far away from a 340 foot redwood tree would you need to stand, if the angle of elevation to the top of the tree is 550? Round your answer to the nearest foot.
Answer:
The required distance away from the foot of the tree is 238.0 feet.
Step-by-step explanation:
The height of the redwood tree = 340 feet, and the angle of elevation to its top = [tex]55^{o}[/tex].
let the required distance be represented by x, applying the appropriate trigonometry function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan [tex]55^{o}[/tex] = [tex]\frac{340}{x}[/tex]
⇒ x = [tex]\frac{340}{Tan 55^{o} }[/tex]
= [tex]\frac{340}{1.4282}[/tex]
= 238.062
x = 238.0 feet
The required distance away from the foot of the tree is 238.0 feet.

Find angles in isosceles triangles...
Answer:
68
Step-by-step explanation:
Given is an isosceles triangle, therefore measures angles opposite to equal sides would be equal.
Hence,
56° + 56° + x° = 180°
112° + x° = 180°
x° = 180° - 112°
x° = 68°
x = 68
Answer:
x = 68°Step-by-step explanation:
The triangle is isosceles as two sides have same length
Angles opposite to same sides have same value, therefore two of them equal to 56°
x = 180° - 2*56°x = 180° - 112°x = 68°Will mark BRAINLIEST!!

A. 4,300 = m / 5,000
B. 4,300 = m x 5,000
C. 5,000 = m / 4,300
D. 5,000 = m x 4,300
Answer:
B
Step-by-step explanation:
The percent of the books that are fiction is 86% and the percent equation is 4300=m×5000. Therefore, option B is the correct answer.
Given that, there are 5,000 books in the town's library.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the percent of the books that are fiction be m
So, m= 4300/5000
4300=m×5000
Percentage =4300/5000 ×100
= 86%
The percent of the books that are fiction is 86% and the percent equation is 4300=m×5000. Therefore, option B is the correct answer.
