Answer:
x = 15.65
y = 3.5
Step-by-step explanation:
Step 1
Find the equation for x and y
Equation for x is given as
x² = 7( 7+28) ..........Equation 1
14(14 + y) = x²........ Equation 2
Solving for Equation 1
x² = 7( 7+28)
x² = 7(35)
x² = 245
x = √245
x = 15.65
From Equation 1 , x² has been determined to be 245
Therefore we substitute 245 for y in Equation 2
14(14 + y) = x²........ Equation 2
14(14 + y) = 245
196 + 14y = 245
14y = 245 - 196
14y = 49
y = 49 ÷ 14
y = 3.5
8.75 or C in your screen is the answer. Simply multiply the length X width.
Answer:
A - x (x+3) = Area of the rectangle
B- 28 inches squared
Step-by-step explanation:
B- using the formula from A
x = 4
x + 3 = 4 +3 = 7
4 times 7 is 28
2/4 is one you could put because 2/4 = 1/2 = 6/12, and 6/12 is less than 7/12.
Glad I could help, and good luck!
