Answer:
(3x - 2)(3x - 4).
Step-by-step explanation:
9x^2-18x+8
Use the 'ac' method:
9 * 8 = 72.
We need 2 numbers whose product is + 72 and whose sum is -18
These are -12 and -6 so we rewrite the expression as:
9x^2 - 12x - 6x + 8 Now we factor by grouping:
= 3x(3x - 4) - 2(3x - 4) The 3x - 4 is common so we have:
(3x - 2)(3x - 4).
The factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic expression is given below.
⇒ 9x² - 18x + 8
Factorize the quadratic expression, then the factors are given as,
⇒ 9x² - 18x + 8
⇒ 9x² - (12 + 6)x + 8
⇒ 9x² - 12x - 6x + 8
⇒ 3x(3x - 4) -2(3x - 4)
⇒ (3x - 2)(3x - 4)
Then the factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).

m&A = (2x + 20°
m&B= (4x - 5)
m&C = (3x + 15)°
m&D = (5x + 16)
me= (2x - 2)
What are the angle measures of each vertex of the garden? Show all calculations and work. Keep in mind that
the drawing may not be to scale.
Answer:
a=82
b=119
c=108
d=171
e=60
Step-by-step explanation:
since we can see the figure has 5 sides we can use the interior angle formula 180(n-2) and replace n for 5 getting 180(3) which woukd get us to 540. with this information we know that all the verticals have to equal 540 so we can add the equations together to get
16x+44=540 - subtract 44 from both sides to get x by itself
16x=496 - simplify
x=31
substitute x for 31 in the equations.

What is the remainder if f(x) = x4 – 5x2 - 6x - 10 is divided by x - 3?
Answer:-46
Step-by-step explanation: just took test
The remainder when f(x) is divided by (x - 3) is 8 and this can be determined by using the factorization method.
Given :
[tex]\rm f(x) = x^4-5x^2-6x-10[/tex]
The following steps can be used in order to determine the remainder if f(x) is divided by (x - 3):
Step 1 - Write the mathematical expression of the statement "f(x) is divided by (x - 3)".
[tex]=\dfrac{x^4-5x^2-6x-10}{x-3}[/tex]
Step 2 - Now, try to factorize the numerator in the above expression.
[tex]=\dfrac{x^4-3x^3+3x^3-9x^2+4x^2-12x+6x-18+18-10}{x-3}[/tex]
Step 3 - Further simplify the above expression.
[tex]=\dfrac{x^3(x-3)+3x^2(x-3)+4x(x-3)+6(x-3)+8}{x-3}[/tex]
[tex]=(x^3+3x^2+4x+6) +\dfrac{8}{x-3}[/tex]
So, the remainder when f(x) is divided by (x - 3) is 8.

Step-by-step explanation:
find x, find jl . any help is deeply appreciated :) !
Answer:
6. x = 15
7. JL = 78
Step-by-step explanation:
6. 8x - 23 = ½(10x + 44) (midsegment theorem)
Multiply both sides by 2
2(8x - 23) = 10x + 44
16x - 46 = 10x + 44
Collect like terms
16x - 10x = 46 + 44
6x = 90
Divide both sides by 6
x = 90/6
x = 15
7. MN = 5x - 16
JL = 4x + 34
MN = ½(JL) (midsegment theorem)
5x - 16 = ½(4x + 34) (substitution)
2(5x - 16) = 4x + 34
10x - 32 = 4x + 34
Collect like terms
10x - 4x = 32 + 34
6x = 66
x = 66/6
x = 11
JL = 4x + 34
Plug in the value of x
JL = 4(11) + 34 = 44 + 34
JL = 78

3/4(12a+8)=31.2 someone please help me solve this:)
Answer:
2.8
Step-by-step explanation:
31.2×4/3
12a+8 = 41.6
12a=33.6
a= 2.8
Answer:
answer is 2.8
Step-by-step explanation:
3/4=0.75
0.75x12=9
0.75x8=6
9a+6=31.2
subtract 6 from both sides
9a=25.2
divide both sides by 9
a=2.8

Pythagorean theorem :)
Answer:
A^2 + B^2 = C^2
Step-by-step explanation:
Your welcome!
Answer:
x = 13
Step-by-step explanation:
In order to solve this you need to know the Pythagorean theorem:
a^2 + b^2 = c^2
a - 1 side
b - 2nd side
c - hypoteneuse
Step 1: Find the missing side of the triangles
** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**
Solve:
17^2 + b^2 = 19^2
289 + b^2 = 361
361 - 289 = 72
√72 = √b^2
8.5 = b (approximately, to the tenth)
Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:
8.5 + 8.5 = 17
Then you subtract it from the base value: 31
31 - 17 = 13
Therefore, x = 13, as that is the remaining of the base.
