Some number was divided into 42. This quotient was then multiplied by 8,after which the resulting product was added to 10. Given
AURORKA [14]

Answer:

126

Step-by-step explanation:

In order to find the initial number, we need to create the expression that is being mentioned and solve for the initial value by applying the opposite expressions to isolate the variable.

(((x / 42) * 8) + 10) = 34   ... subtract 10 from both sides

((x / 42) * 8) = 24 ... divide both sides by 8

(x / 42) = 3  ... multiply both sides by 42

x = 126

Finally, we can see that the initial value was 126

First find the area of the triangle.

\sf A=\dfrac{1}{2}bh

\sf A=\dfrac{1}{2}(6)(12)

\sf A=36cm^2

ABCE is a parallelogram, this means that the area of triangle ABE is equal to the area of triangle EBC. The are of the entire trapezoid is 180 square centimeters, we already found the area of the triangle, so that leaves us with:

\sf 180-36=144

So the area of the entire parallelogram must be 144 square centimeters. So each half of the parallelogram must be equal to:

\sf 144\div 2=\boxed{\sf 72cm^2}
