PLEASE PLEASE PLEASE HELP Multiply the polynomials (3^2 − 5 + 7) and (2^2 + − 2). Simplify the answer. Show your work.

22

Step-by-step explanation:

(3² - 5 + 7) × (2² - 2)

(9 - 5 + 7) × (4 - 2)

(4 + 7) × (2)

11 × 2

22

Use the order of operations (PEMDAS- parentheses, exponents, multiplication and division, addition and subtraction) to solve.

(3^2-5+7)x(2^2-2)

(9-5+7)x(4-2)

(11)x(2)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
