The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation <span>9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
</span>using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +-

/ 2(9)
Answer:
-7 and -5
Step-by-step explanation:
-7 and -5 added together are -12, and their product is 35.
A is the answer to this question no doubt
Answer:
Part A: 7.58974359 gallons (I don't know if you needed to round so I kept the full number).
Part B: 8.871794872 gallons
Step-by-step explanation:
Part A's Steps:
First Step: 350 - 54 = 296
Second Step: 296 ÷ 39 = 7.58974359 (Round if you need to)
Part B's Steps:
First Step: 296 + 50 = 346
Second Step: 346 ÷ 50 = 8.871794872
I'm sure the measurement was made in grams because:
1. most cell phones weigh between about 100 and 150 grams
2. there's no cell phone that weighs 113 kg, 113 pounds, 113 ounces etc.
