23 inches
x = mindy's height
2x - 20 = 66
-20 -20
2x = 46
/2 /2
x = 23
This is an excellent practice for the solution of quadratic equations.
1*36=36 => (1,36)
2*18=36 => (2,18)
3*12=36 => (3,12)
4*9=36 => (4,9)
6*6=36 => (6,6)
9*4=36 => (9,4)
12*3=36 => (12,3)
18*2=36 => (18,2)
36*1=36 => (36,1)
We can see that the sum decreases until the two factors are close (or equal) and then increases again.
The pair of integers with a sum of 20 is therefore (2,18) or (18,2).
A) y=2x2-28x+52 ion think it’s any other but I might be wrong
Y=<span>2 is your answer. Hope this helps :)</span>
