Dimensions:
(x-3)
(x+2)
Perimater = sum of sides:
Perimeter = 14 in
Replacing:
14 in = 2 (x-3) + 2 (x+2)
Solve for x :
14 = 2x-6 + 2x + 4
combine like terms:
14 = 2x+2x-6+4
14 = 4x - 2
14+2 = 4x
16 = 4x
16/4 = x
x = 4
Dimensions:
(x-3) = 4-3 = 1
(x+2) = 4 + 2 = 6
Answer:
20 gallons
Step-by-step explanation:
Divide 120 miles by 8 to find miles per gallon
120 ÷ 8 = 15 miles per gallon
Now divide 300 miles by 15 to find number of gallons required
300 ÷ 15 = 20
20 gallons are required for a journey of 300 miles
Answer: D
So we want to find out how big all the sides are to find out if its less than 400
do in calc
2(13x5)+2(8x5)+2(13x8)=418
418>400
and its d because its talking about the surface area since we are trying to cover the surface in wrapping paper
-5t+5t+2+8-8
-5t+5t=0 or t
2+8-8=2
t+2 is the final answer
