Bottom rectangle = 10*7 = 70
Top rectangle = 8*7 = 56
Side rectangle = 6*7 = 42
Side triangle = (1/2)*8*6 = 24
Side triangle = (1/2)*8*6 = 24
--------------------------------------------------
Total surface area = 70+56+42+24+24 = 216

Step-by-step explanation:
Answer:
D) Abner can spend $60 per month on school clothes and $20 per month on gym clothes and stay within his budget.
Step-by-step explanation:
In the problem it states that Abner will spend 3 times more on (s)school clothes than (g) gym clothes.
So it would appear as s ≥ 3g.
If we plug in $60 as s (school clothes) and $20 as g (gym clothes), the statement is true.
60 ≥ 3(20)
60 ≥ 60. These numbers make the linear system true.
If you have trouble with this, an easy way to find this answer is simply creating the linear system that represents the problem, (he will buy 3 times more school clothes than gym clothes) s ≥ 3g and plug in each variable from the answer choices until you find the variables that make the linear system true.
Standard form is Ax + By = C
Where A is a positive integer
The y needs to be moved to the left side so subtract 3y from both sides.
2x - 3y = -8
Hello!
We have been given enough information to answer this question!
We know that a square has four sides, and each of its sides are of equal length. We also know that the sides measure 2 feet long.
The rectangular painting is made up of two congruent squares. Congruent means they are the same.
The formula for the area of a square is:
A = a (squared)
Substitute:
A = 2 × 2 = 4
So, the area of one square is 4 ft. That means the area of both of the squares combined would be 8 ft.
So, the area of the entire painting is 8 feet squared. (Write a small two just above feet to indicate that it is squared).
