Evaluate the expression

An algebraic expression of the sum or difference of two terms

Determine if  $a\left(b-6\right)\ and\ a^2+b+9\$  are EQUIVALENT if  $a=3\ and\ b=18$  

Which of the following are polynomials of degree 4? Check all that apply.

Evaluate $2\left(a-5\right)+2$  when a=15

(a)  

In the expression $4a^3-6b^2+14c+20$ 

, the numbers 4, -6, and 14 represent ....

If given the expression $7a^2+14x-6\$  where  $a=10$  and  $x=3$  , which example below shows how to correctly substitute the values of "a" and "x"?

If I were to substitute a=10 and x=3 into the expression $7\left(a\right)^2+14\left(x\right)-6$  , I would get  $7\left(10\right)^2+14\left(3\right)-6$  . What is the simplified value of this expression?
