Perimeter = (x+2) + x + (x+2) + x
Perimeter = 4x + 4
Area = x(x+2)
Area = x^2 + 2x
One fifth of a number n is equal -7 as an equation would look like this:
1/5 n = -7 / * 5 (both sides)
n = -35
So if number n equals -35, then it's true that 1/5n equals -7.
Would it be distribution were you multiply the three in? -3(b-7) -3*b and -3*-7 where your answer would be -3b+21
2/5 i believe
because a coin has two sides ( heads or tails) then the spinner is 5 equal sections so 2/5 <3
hope it helps
