A: If the 1st side of the garden is x feet long then the other sides are 2x - 5. The perimeter is simply the measure of the distance around the triangle, so the length of all three sides added up. So the equation to find the perimeter (p) would be...
p = x + (2x+5) + (2x+5)
or
p = x + 2(2x+5)
This is actually an equation so the expression to represent perimeter would simply be...
x + 2(2x+5)
B: Since we know the equation for the perimeter and we know that we have 40 feet of fencing, then the equation to find the left over fencing would just be the length of fencing minus the perimeter...
40 - x + 2(2x+5) = the leftover amount of fencing
so the expression is...
40 - x + 2(2x+5)
This is number 8. the second person got number 9
Answer:
A. Diego's answer is not correct.
B. 0.00375
Step-by-step explanation:
a. As I counted the thickness of the paper I realized that 0.015 inches is way too think because if we stacked 500 of those it would be 7.5 inches tall.
b. 1.875 ÷ 500 = 0.00375. so that is your answer
