Answer:
14 is real number the A no . answer
Length of rectangular = 3w
P=2L+2w
32=2L+2w
16=L+w
16=3w+w
16=4w
w=4
L=3*4=12
Area= Lw
Area=12*4= 48 ft^2
It would be 7x7 + 2x2 = 53
Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours
