Answer:
B= (-1, 7)
Step-by-step explanation:
Midpoint formula is X1 plus X2, then divided by 2. So, because the midpoint is given you work backwards. So for the x value do (-3 + x) divided by 2 equals -2 and solve for x and you do the same thing for the Y value
x = 9
The sides on the left are proportional and can be used to find the sides on the right.
Since 72/8=9, 56/8 must equal 3x-20
Let x equal a number
3x + 5 = 26
3x = 21
x = 7
the number is 7!
