Answer:
Inequality : 4x+8 < 120
x<28
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P)= 2 length +2 width
Where:
Width = x
Length = x+4
Replacing with the values given
P = 2 (x+4) + 2x
P = 2x+8+2x
P=4x+8
Since the perimeter of the rectangle must be less than 120:
4x+8 < 120
Solving for x
4x<120-8
4x<112
x<112/4
x<28

The area of the circle would be 0.97
Bill = 4b + 2.
Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.
