Answer:
4) 2(x - 3)^2 + 2(y + 5)^2 = 96.
Step-by-step explanation:
2x^2 – 12x + 2y^2 + 20y – 28 = 0
2(x^2 – 6) + 2(y^2 + 10y) = 28
2 ( (x - 3)^2 - 9)) + 2((y + 5)^2 - 25) = 28
2(x - 3)^2 - 18 + 2(y + 5)^2 - 50 = 28
2(x - 3)^2 + 2(y + 5)^2 = 28 + 18 + 50
2(x - 3)^2 + 2(y + 5)^2 = 96
112.50 divided by 15 is 7.5= 7.50 so 7.50 times 10 is $75.00 so answer is $75.00
3 × 4 × 5 = 20 · x
12 × 5 = 20x
60 = 20x
20 20
3 = x

Answer:
Henry rented the backhoe for three days
Step-by-step explanation:
It's simple. First, you suppose that the number of days he rented the backhoe is 'm'. Then you equate the bill to the amount that corresponds the number of rented days.
The bill came for 286.50$. That'd mean, m*95.50$ = 286.50$ => m = 286.50/95.50 = 3
