Answer:
A
Step-by-step explanation:
$38.95 for 3 m size pizzas and a salad
38.95 = 3m + 11.98
32,000 x .09 = 2880
$2880 budgeted for clothes yearly
1. 7x + 9 = 48
7x = 58 - 9
7x = 49
X = 7
Answer:
= 3^9
Step-by-step explanation:
The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
