A rectangle has one side 3cm longer than the other. Write an expression for the area.
Answer:
W = width
A = area
A = (W+3)(W)
A = W^2+3W
A horizontal line includes the points (0, -2) and (3, -2). Find the slope of the line.
wil give BRAINLIEST
pls answer correctly
Answer:
We conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
[tex]m = 0[/tex]Step-by-step explanation:
Given that the line includes the points
(0, -2)(3, -2)We need to find the slope of the line containing the points between (0, -2) and (3, -2) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (0, -2)(x₂, y₂) = (3, -2)now substituting (x₁, y₁) = (0, -2) and (x₂, y₂) = (3, -2) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-2-\left(-2\right)}{3-0}[/tex]
[tex]m=\frac{-2+2}{3}[/tex]
[tex]m=\frac{0}{3}[/tex]
[tex]m = 0[/tex]
Therefore, we conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
[tex]m = 0[/tex]Consider the quadratic expression given below.
4x^2 + 8x - 60
Factor the following expression completely.
Answer:
4(x + 5)(x - 3)
Step-by-step explanation:
Given
4x² + 8x - 60 ← factor out 4 from each term
= 4(x² + 2x - 15) ← factor the quadratic
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3 , since
+ 5 × - 3 = - 15 and + 5 - 3 = + 2, then
x² + 2x - 15 = (x + 5)(x - 3)
Then
4x² + 8x - 60 = 4(x + 5)(x - 3) ← in factored form

What are important things to think about when justifying a conjecture?
Answer:
Step-by-step explanation:
First, we need to understand what a conjecture means, we can take a conjecture to mean the use of observed patterns or foundational knowledge about a certain phenomenon or thing to make a decision or make a logical conclusion about such thing.
Hence, when making Justification about a conjecture, we need to take into cognizance some potent things :
1.) There must be an observed pattern, relationship between the observation upon which a conjecture is to be made. As this pattern are key to our reasoning and decision.
2.) Also, our final conclusion or conjecture will be based on the pattern observed and not on some random thought.
Find two integers whose sum is -9 and product is -10
Step-by-step explanation:
if the two integers are x and y
xy=-10
x+y=-9
x+(-10/x)=-9
x2+9x-10=0
(x-1)(x+10)=0
x=1 or x=-10
if x=1, y=-10
if x=-10, y=1
so the two integers are 1 and -10
8. The similarity between an ordinal level of measurement and an interval level of measurement is that
A. neither can be arranged in some order
B. both can be arranged in some order
C. differences between data values can be determined and are meaningful
D. differences between data values cannot be determined or are meaningless
Answer: B. both can be arranged in some order
Step-by-step explanation:
At the ordinal level of measurement, data can be ordered in some format however it is not possible to know how much the data vary from each other. For instance: Very Bad, Bad, Good, Very Good. Data can be ordered under this but we won't know just how much of a difference exists.
Interval data can also be ordered and this time we can tell how the data varies from one another for instance by 1 or 2. The only problem here however, is that interval data does not end with zero.

GCF AND LCM
Step-by-step explanation:
We need to do LCM in this case.
2_|_ 6,4,16
2 _|_ 3,2,8
_|_ 3, 1,4
It is not divisible further.
So, LCM is 2×2×3×4 = 48
So, 48 is the answer.

Answer:
= -4(2.3x + 0.7)
Step-by-step explanation:
=(3x + 5.1) + (-12.2x - 7.9)
= 3x + 5.1 - 12.2x - 7.9
= -9.2x - 2.8
= -4(2.3x + 0.7)

3 teas and 2 coffees have a total cost of £7.80.
5 teas and 4 coffees have a total cost of £14.20.
Work out the cost of one tea and the cost of one coffee.
Answer:
coffee is £1.80 per cup and tea is £1.40 per cup
Step by Step:
The question can be written algebraically, as:(a) 3t + 2c = 7.80(b) 5t + 4c = 14.20To work out the individual costs, we need to make one of the sets of variables equal. We can do this by multiplying the equation (a), giving (c):(a) 6t + 4c = 15.60(c) 5t + 4c = 14.20We can then subtract (c) from (a), giving:t = 1.40T can then be substituted into the initial equation (a), to work out the value of c:(3 x 1.40) +2c = 7.804.20 +2c = 7.802c = 3.60c = 1.80Finally we can check these values by substituting into (b):(5 x 1.40) + (4 x 1.80) = 7 + 7.2 = 14.20Then make sure to show your answers clearly, with units:coffee is £1.80 per cup and tea is £1.40 per cup

On a map, 1 inch equals 5 miles. Two cities are 3 inches apart on the map. What is the actual distance between the cities?
The actual distance between the cities is ___ miles.
Answer:
15
Step-by-step explanation:
cross multiplying, [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{x}[/tex]
then it would be 15 =1x
and 1x is basically just one, so 15 = x

On Thursday, G00gle announced that one of its employees, Emma Haruka Iwao, had found nearly 9 trillion new digits of pi, setting a new record. Humans have now calculated the never-ending number to 31,415,926,535,897 (get it?) — about 31.4 trillion — decimal places.
Sam wants to enlarge a triangle with sides 3, 6 and 8 inch sides. If the shortest side of the new triangle is 5.4 inches, what is the perimeter of the enlarged triangle?
Answer:sides of triangle = 3,6,8
sides of enlarged triangle = 5.4, x.y
3/ 5.4 = 6/x = 8/y
3/ 5.4 = 6/x
3x =5.4*6
3x =32.4
x = 10.8
3/5.4 = 8/y
3y =8 * 5.4
3y = 43.2
y = 14.4
perimeter = 5.4 +10.8 +14.4 =30.6 inches

This problem says to write the product of the sum and the difference. (x+5)(x-5). I'm not sure what my teacher is asking me to do.
Step-by-step explanation:
step 1. x + 5 and x - 5 are polynomials.
step 2. x + 5 is a sum, x - 5 is a difference.
step 3. (x + 5)(x - 5) is a product which means to multiply. So "multiply" using FOIL.
step 4. (x + 5)(x - 5) = x^2 - 5x + 5x- 25 = x^2 - 25.
