A football team won 75% of 120 games in a season. How many games is that?
Luba_88 [7]

Answer:

90 games

Step-by-step explanation:

Of the 120 games the football team played, they won 75% of them.

Remember that in mathematics, "of" almost always means to multiply. Here, that means we must multiply 75% by 120:

75% * 120

Remember also that % just means divided by 100, so 75% = 75 / 100. So:

75% * 120 = (75/100) * 120 = 9000/100 = 90 games

Factor the polynomial: 3x(x-6) + 8(x-6)
neonofarm [45]

Answer:

C

You just split the equation, as the brackets are both same. If you take (x-6) out, it will leave you with 3x+8.

Therefore, (x-6)(3x+8) is the answer.
