Answer:
- 10b² + 12b - 16
Step-by-step explanation:
b² + 8b - 9 - (11b² - 4b + 7) ← distribute by - 1
= b² + 8b - 9 - 11b² + 4b - 7 ← collect like terms
= (b² - 11b²) + (8b + 4b) + (- 9 - 7)
= - 10b² + 12b - 16
P^4 - 25p^2 + 144
My working out is in the picture
4+.95=4.95
4.95*3= 14.85
The student paid $14.85 for the three cans.
