Answer:
A
Step-by-step explanation:
Equation
2x + 3x + 8 + 7x - 2 = 90
Solution
Combine like terms on the left
12x + 6 = 90 Subtract 6 on both sides
12x = 90 - 6
12x = 84 Divide by 12
x = 84/12
x = 7
Answer:
39 square feet
Step-by-step explanation:
P = 2( L + W)
actual length = 4 * 3 = 12
actual width = 2.5 * 3 = 7.5
P = 2 (12 + 7.5)
P = 2 ( 19.5)
P = 39 feet
1. {x}^{2} - 25x = 0
2. {y}^{2} - 64
3. {x}^{2} + 2x - 48
