Answer:
<h2>x=2 , x = 6</h2>
Step-by-step explanation:
x² – 8x = 20 ⇌ x² – 2(4)x = 4 + 16 ⇌ x² – 2(4)x - 16 = 4 ⇌ (x - 4)² = 4
⇌ x - 4 = 2 or x - 4 = -2 ⇌ x = 6 or x = 2
Answer:
4.5
just follow the rules of finding percents and you will find you answer
-2 x=10
-2 x/-2=10/-2
x=-5
Or
17.5
Divide 7 by 8 to get .875 and multiply that by 20 to get your answer.
