EVALUATING EXPRESSIONS
Part I Evaluate each expression, using the given values of the variables:
a. b. c. d. e. f.
3+w whenw=11
A-12whenA=27 6xwhenx=25
b/3 when b = 144 23-y+2wheny=-19 6z/18 when z = -12
Part 2 - Evaluate each expression, using the values x = 13 and y = 7
a. x + y
b. x - y
c. Xy
d. x/y
e. 2x + y
f. x+2y
g. 2x+2y
h. 4x-3y
i. x +y-x-y
j. 7x-13y
Part 3 - Use the values a = 5, and b = 3 to evaluate each expression:
a. 3(a + b)
b. (a+b) - 7
c. 4(2a + b)
d. 6(a-b)+5
e. (a+b)(a -b)
f. (2a + b)(2a -b)
g. 3(b + a)
h. 4(b + 2a)
Part4: Ifm=12andp=-1,findthevalueof3m-2p

Brook states that the distance on the line is 4 units. caleb states that the whole line does not have a distance because it continues on forever. vivian states that the line is 6 units long. which distance did brook measure? which distance did vivian measure?

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit
