Your answer would be B. William will pay $392.30 with his, and at the store he'll pay $402.15. :)
Answer:
x=42 degrees
y= 66 degrees
z=66 degrees
Step-by-step explanation:
X is equal to 42 degrees because all angles in a triangle add up to 180, and since we are given two angles of the triangle, we can add them, then subtract the answer from 180.
48+90=138
180-138=42
Therefore x is 42 degrees.
For angle y and z, they are made up of 3 angles that equal 180. We have one angle measurement given, 48. So we would subtract that from 180, then divide the answer by 2.
180-48=132
132/2=66.
Therefore y and z is 66 degrees.

Answer: 2x³(x² + 5x - 11)
<u>Step-by-step explanation:</u>
2x⁵ + 10x⁴ - 22x³
Factor out the GCF (2x³)
2x³(x² + 5x - 11)
Since there are no values whose product is -11 and sum is +5, this cannot be factored further.
