Answer:
Step-by-step explanation:
10
Answer:
5
Step-by-step explanation:
This is a pretty simple question to answer, the one step that needs to be done is divide 78.5 by 15.7. You should come up with 5.
L would measure at 54°. Because the angels of a triangle measure up to 180, you can set the equation up like this: 5x + 3x + 2x = 180. These are like values, so you can add them together to simplify a bit, yielding 10x = 180. Divide 180 by 10 to get x by itself, giving you 18. L = 3x, so 3(18) = 54.
Answer:
- 4x² + 6xy - y²
Step-by-step explanation:
8x² + 3xy + 4y² - 12x² + 3xy - 5y² ← collect like terms
= (8x² - 12x² ) + (3xy + 3xy) + (4y² - 5y²)
= - 4x² + 6xy - y²
