Let’s make an equation
Let’s say x = amount of years after
Smith = 8, mother = 42
3(8 + x) = 42 + x
24 + 3x = 42 + x
2x = 18, x = 9
Solution: after 9 years
Answer:
This question doesn't really make sense...
Step-by-step explanation:
Please try to correct it.
So area is base x height:
5(x+2)=20
5x+10=20
5x=10
x=2
its A
F= 9 x 7 = 63
G= 19 x 4 = 76
H= 12 x 4 = 48
J = 32 x 2 = 64
J is the answer
