Answer: x=2
Step-by-step explanation:
-4x+7=-1
-4x=-8
x=2
The other answer is wrong. It says 4 round trips so 4x2=8. So 8x47 is your answer

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'.
Answer:
x+3
Step-by-step explanation:
sqrt(x^2+6x+9)
factor
We know this is a perfect square trinomial
sqrt(( x+3)^2)
Taking the square root of a square
x+3
