You add all the sides together, a good way to remember it is "perimeter, plus"

Answer:
The answer is n = <u>31</u>
Step-by-step explanation:
Equation: <u>2n + 13</u> = 75
2n = 75 - 13
2n = 62
n = 62/2
n = 31
check:
2*31 + 13 = 75
62 + 13 = 75
Total blocks = 35+47+22+21 = 125
Sum of red blocks and green blocks = 47+35 = 82
So the probability = 82/125 = 0.656
Recall that the slope or gradient of a line segment through two points is the ratio of the change in the <em>y</em> coordinate to the change in the <em>x</em> coordinate.
If the gradient is 1, then
1 = (-3 - 4) / (<em>a</em> - 3<em>a</em>)
Solve for <em>a</em> :
1 = -7 / (-2<em>a</em>)
1 = 7/(2<em>a</em>)
2<em>a</em> = 7
<em>a</em> = 7/2
