Which are steps that could be used to solve 0 = 9(x2 + 6x) – 18 by completing the square? check all that apply.
18 +81 = 9(x2 + 6x +9)
18+9 = 9(x2 + 6x +9)
18+ 36 = 9(x2 + 6x + 36)
11 = (x + 3)2
1342 = (x + 6)2
799 = (x + 3)2

5 1/3 grams per serving

Step-by-step explanation:

Find the unit rate. 4 grams for every $\frac{3}{4}$ serving The unit rate is grams per serving.

The unit rate in grams per serving is given as:

3/4 servings = 4 grams

1 servings = x grams

Cross Multiply

x grams = 4 grams × 1 serving/3/4 serving

x grams = 4 grams ÷ 3/4 servings

x grams = 4 grams × 4/3 servings

x grams = 16/3

x grams = 5 1/3 grams per serving

The unit rate = 5 1/3 grams per serving
