Answer:
25.35
Step-by-step explanation:
Area of the shaded portion = Area of semicircle - Area of the right triangle
Area of semicircle = πr²/2
Area of semicircle = 3.14(6)²/2
Area of semicircle = 3.14 * 18
Area of semicircle = 56.52
Area of triangle = 1/2 * base * height
Get the height using the SOH CAH TOA identity
sin 60 = H/12
H = 12sin60
H = 12(0.8660)
H = 10.39
Get the base
12² = b²+10.39²
144 = b²+108
b² = 144 - 108
b² = 36
b = 6
Area of triangle = 1/2 * 6 * 10.39
Area of triangle = 3 * 10.39
Area of triangle = 31.17
Area of shaded portion = 56.52 - 31.17
Area of shaded portion = 25.35
If it's an equation, such as y=mx+b, the slope is whatever the value of m is. For example, if the equation was y=2x-4, than the slope would be 2.
When solving this on a graph, choose any 2 whole number points. (preferably close together, because it makes it easier) Count how many lines up/down (the y axis) and how many lines over left/right (the x axis) and put the up/down on the top of a fraction and the left/right on the bottom. for example if up was 2, and right was 3, than it would be 2/3. Down is negative, and to the left is also negative. If there are 2 negatives (one on the top and one on the bottom) than they cancel each other out and become positive. For example: -2/-3 would be the same as 2/3. Hope this helps :)

PLEASE GIVE ME BRAINLIEST and I hope this answer helped!!!
Answer:
a. 13
Step-by-step explanation:
x - youngest sister
x + 1 - middle sister
x + 1 + 1 - oldest sister
x + x + 1 + x + 1 + 1 = 39
3x + 3 = 39
3x = 36
x = 12
x+ 1 = 12 + 1 = 13
