Answer:
2
- 5x² - 63
Step-by-step explanation:
Given
(2x² + 9)(x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
2x² (x² - 7) + 9(x² - 7) ← distribute both parenthesis
= 2
- 14x² + 9x² - 63 ← collect like terms
= 2
- 5x² - 63
Step-by-step explanation:

Answer:
y=1/2x+3
Step-by-step explanation:
grabbing two points in this case (0,3) and (2,4)
we use the rise over run formula meaning it rises 1 and runs 2 so our slope is 1/2
to get the y intercept just look at where the line touches the y line in this case at 3
using the equation y=mx+b and m is slope and b is y interecpt we plug in the numbers
so we get y=1/2x+3
380 - 18% of 380
= 380 - (18/100)×380
= 380 - 68.4
= 311.6
