Which number sentences show how to solve the problem? the bowling club donated 4 crates of orange juice for the neighborhood picnic. the soccer club donated 12 crates of mixed juices for the picnic. each crate holds 32 juice boxes. how many juice boxes were donated altogether for the picnic? choose all answers that are correct. a. 4 + 12 = 16 and 16 × 32 = 512 b. 4 × 32 = 128 and 128 × 12 = 336 c. 4 × 32 = 128, 12 × 32 = 384, and 128 + 384 = 512 d. 4 + 12 = 16 and 16 × 21 = 336

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.
