Answer:
D:315
Step-by-step explanation:
6x7 and then divide by 2 = 21+21 =42 13x7= 91x3= 273+ 42= 315
Degree is the value of the highest power of the variable, and hence in this case is 8
Answer:
f
Step-by-step explanation:
I'm pretty sure it's f from what I know
In order to calculate the compound amount and the amount of interest earned, we can use the formula below:
Where A is the compound amount after t years, P is the principal (initial amount) i is the interest rate and n is how many times the interest is compounded in a year.
So, for P = 71000, i = 0.0102, t = 4 and n = 4, we have:
Therefore the compound amount is $73952.87
The amount of interest is:
So the amount of interest earned is $2952.87.

Answer: 100 degrees</h3>
===============================================================
Explanation:
The two angles that involve x are alternate interior angles.
Due to the parallel lines, the alternate interior angles are equal.
We'll use this to solve for x
-7x-18 = -9x-46
-7x+9x = -46+18
2x = -28
x = -28/2
x = -14
Let's check the answer by evaluating each expression as shown below
- -7x-18 = -7*(-14)-18 = 80
- -9x-46 = -9*(-14)-46 = 80
Both angles are 80 degrees each, so it confirms we have the correct x value.
-----------------------
We have one last step. We found the -9x-46 angle to be 80 degrees. Angle 4 is adjacent to this and supplementary.
So we subtract from 180 to get the answer
180-80 = 100
