Answer:
Step-by-step explanation: Step 1: Simplify both sides of the equation.
3(y+8)=36
(3)(y)+(3)(8)=36(Distribute)
3y+24=36
Step 2: Subtract 24 from both sides.
3y+24−24=36−24
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
Answer:
Volume = 42 units^2
x = 5 units
Total Surface Area = 96 units
Step-by-step explanation:
Volume
V = bh, where b = 1/2 * 3 * 4 and h = 7,
= 6 * 7 = 42 units^2
x
You can solve for this variable by using the pythagorean theorem;
a^2 + b^2 = c^2, where a = 3 and b = 4,
9 + 16 = x^2
= 25 = x^2
= x = 5 units
Total Surface Area
You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:
7 * (3 + 4 + 5) + 2(1/2*3*4)
= 7*12 + 12
= 96 units
Answer:


- We want to remove the 2 first. Since the original equation is + 2 , we're gonna use the opposite operation and subtract 2 form both sides.

- Simplify! 2 - 2 = 0 on the left and 26 - 2 = 24 on the right.

- Then we need to think about how to remove the coefficient 12 . Since the opposite of multiplication is division , we're going to divide both sides by 12.

- Simplify. 12/ 12 = 1 on the left and 24 / 12 = 2 on the right. So our answer is x = 2 .
