Answer:
perimeter: 22x-14
area : 24x^2-37x
Step-by-step explanation:
for perimeter, it is the length of all the sides added together
starting at the left and working clockwise
5x+((6x-7)-(3x+1))+2x+(3x+1)+(5x-2x)+(6x-7)
5x+6x-7-3x-1+2x+3x+1+5x-2x+6x-7
combine like terms
perimeter: 22x-14
for area, area of (5x*(6x-7)) and subrtact the missing portion of (2x*(3x+1))
(30x^2-35x)-(6x^2+2x)
area : 24x^2-37x
Answer:
Step-by-step explanation:
Answer:
B. 1,500’
Step-by-step explanation:
Given;
dimension of the rectangular house, = 35’ x 40’
The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'
The rough estimate should be greater than the actual estimate in 100s;
rough estimate = 1,400' + 100' = 1,500'
Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.
