Ann-x
Cori-3x
3x+x=124
4x=124
divide both sides by 4
x=31 now plug it in and you get
Ann-31
Cori-31×3=93
Ann spent 31$
Cori spent 93$
The answer is x = 2a^3 - 3a
A: 5+5+6=11 units
B. You can find the height by dividing the traingle into 2 right traingles with 5 being the hypotenuse and 3 being one of the legs.
5^2=3^2+x^2
25=9+x^2
16=x^2
x=4
Area= 6*4/2= 12 units^2
C. 12*6=$72
