The answer is 42... you add 56 and 82 then subtract that sum from 180
Perimeter = Side + Side + Side
Side 1 = x
Side 2 = x + 7
Side 3 = 2x-7
Plug into the equation:
84 = x + (x + 7) + (2x-7)
84 = x + x + 7 + 2x - 7
Combine like terms:
84 = 4x
Divide by 4 and solve for x:
21 = x
Side 1 = 21
Side 2 = 28
21+7=28
Side 3 = 35
21(2) - 7 = 42 - 7 = 35
Answer:
a = 10/3
Step-by-step explanation:
This can be written as:
Anything to the power of 1/3 means to find the cube root. We can simplify this to:
I just multiplied 4 and 1/3 (because of the second index law 
). Now, we can add the powers because the bases are the same and we are multiplying (first index law):
a = 10/3

Answer:
5x • (x + 3y) • (x - 2y)
Step-by-step explanation:
Given that the US population is approximately 308,000,000 in 2010 and that 6.5% of this population is under 5 years of age, we will know that number of children by multiplying 6.5% by 308,000,000. So the answer would be 20,020,000. So that is the number of children below 5 years old. Hope this helps.
