Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction
first you're going to want to do 56 / 14.
If the q is: are 4z2-22 and 4 equivalent expressions, the answer is No.
4z2-22=4
8z-22 is not equal to 4
If you are looking for value of z, then:
8z-22=4
8z=4+22
8z=26
z=26/8
z=13/4
In case in which z=13/4, than expression
4z2-22 would be equivalent to 4.
Hope this helped.
