Answer:
D (x-10)
Step-by-step explanation:
x^2 - 8x - 20
(x -10)(x+2)
Set up a system of equations.
X+y=6
Y-x =40
Substitution method.
Y=6-x
(6-x)-x =40
6-2x=40
-2x=34
X= -17
Plug it back into the equation.
-17+y=6
Y=33
(-17,33) is one of the possible answers.

mama giraffe: x
baby giraffe: 
= 15
= (3)15
3x + 2x = 45
5x = 45
x = 9
baby giraffe: = 
= 2(3) = 6
Answer: 6 m
The didn’t distribute the -6 properly to the fraction the second part of solving should have been -6(4x)+((-6)-2/13)
