A + 3^3− (b − a); use a = 1, and b = 6

23

Step-by-step explanation:

Let a = 1 and b = 6.

Use the order of operations to evaluate the expression:

Parenthesis → Exponents → Multiplication → Division → Addition → Subtraction

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
