0=8x^2+8x-21 in (x-p)^2=q form

Mathematics
1 answer:
Makovka662 [10]2 years ago
7 0

Step-by-step explanation:

8x² + 8x - 21 = 0

8(x² + x) - 21 = 0

8(x + 0.5)² - 23 = 0

8(x + 0.5)² = 23

(x + 0.5)² = 23/8.

Gracie earns $7 for each car she washes. she always saves $25 of her weekly earnings. this week, she wants to have at least $65
nata0808 [166]
65 divided by 7 is approximently 9, and 25 divided by 7 is approximently 3, so 9 plus 3 is 12, so Gracie must wash 12 cars to earn enough money to save 25 and spend 65!
