Evaluate the following expressions if a = 2, b = 3, x = 4, and y = 5.
b^2+3(2x-y)

Hi there! Hopefully this helps!

-------------------------------------------------------------------------------------------------------

First we need to substitute the value of the variable into the expression.

= .

Now we need to solve .

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First, calculate 3 to the power of 2 and get 9.

Multiply 2 and 4 to get 8.

Subtract 5 from 8 to get 3.    

Multiply 3 and 3 to get 9.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
