Answer: x = -3
Step-by-step explanation: hope this helps
23 – 7x + 6 + 8x = 26
x + 29 = 26
x + 29 - 29 = 26 - 29
x = 26 - 29
x = -3
-3^2= -(3)^2
The exponent of 2 only applies to the number 3. -(3)^2 should equal -9. This is true because according to the order of operations, exponents should be evaluated before multiplication. The negative sign here represents -1* 3^2.
If you want to find -3 to the power of 2 it must be written (-3)^2.
