If you would like to solve (n^3 - n^4) - (3n^3 - 7n^4), you can do this using the following steps:
(n^3 - n^4) - (3n^3 - 7n^4) = <span>n^3 - n^4 - 3n^3 + 7n^4 = n^3 - 3n^3 - n^4 + 7n^4 = -2n^3 + 6n^4
</span>
The correct result would be <span>-2n^3 + 6n^4.</span>
Answer:
13
Step-by-step explanation:
to find the length between two point you've got to use the formula
√(x2-x1)^2 +(y2-y1)^2
√(-2-3)^2 + (-4-8)^2
√(-5)^2 + (-12)^2
√ 25+144
√169
13
Step-by-step explanation:
due to the rules of crossing lines and their angles, the 2 angles opposite of each other must be equal.
so,
7x + 7 = 112
7x = 105
x = 15
You can use a calculator for this if you have the graphing kind (I use a Ti-84) and when plugging the equation in, the answers should be b, d, and e
