Answer:
Step-by-step explanation:
<u>Using slope formula to find the value of k:</u>
- (-9 - k)/(-2 - (-4)) = - 9
- (-9 - k)/2 = - 9
- - 9 - k = - 18
- k = 18 - 9
- k = 9
Answer: It is a 40 degree angle
If the formula is V= Ab x H
then the base and height is 4 and 7.5 because it doesn’t need to be the bottom so you multiply 7.5 x 4= 30 but we have to half it since it’s a triangle which is 15 and then multiply 10 which gives us 150 cm squared.
Answer:
x^3 + x^2 + x
Step-by-step explanation:
3x^3 + 4x^2 − (2x^3 + 3x^2 − x)
Distribute the Negative Sign:
=3x^3 + 4x^2 + −1 (2x^3 + 3x^2 − x)
=3x^3 + 4x^2 + −1 (2x^3) + −1(3x^2) + −1 (−x)
=3x^3 + 4x^2 + −2x^3 + −3x^2 + x
Combine Like Terms:
=3x^3 + 4x^2 + −2x^3 + −3x^2 + x
=(3x^3 + −2x^3) + (4x^2 + −3x^2) + (x)
=x^3 + x^2 + x
