The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
24 x 8 = 192
192 / 2 = 96
I am not sure if my answer is true.
A² + b² = c²
Where a and b are the legs and c is the hypotenuse
So, plug in 10 for one of the legs and 24 for the other leg
c will be left blank because that is what you are trying to find, the hypotenuse
10² + 24² = c²
100 + 576 = c²
676 = c²
Take the square root of both sides of the equation to isolate c
√676 = √c²
Square of c and the square root cross out on the right
Take the square root of 676
c = 26
So, the length of the hypotenuse is 26 centimeters
Take the cube root of 216. You will get 6
