Answer:
2646/100 or 260 46/100 or 260 23/50
-3 degrees
To find the average temperatures, you add them all together (-5 + -7 + -2 + 2 + -3 = -15) and divide that number by the number of terms added together (-15/5 = -3)
(x³ - 2)(3x² - 1) + r = 3x⁵ + 3x³ + 2x² + x + 2
x³(3x² - 1) - 2(3x² - 1) + r = 3x⁵ + 3x³ + 2x² + x + 2
x³(3x²) - x³(1) - 2(3x²) + 2(1) + r = 3x⁵ + 3x³ + 2x² + x + 2
3x⁵ - x³ - 6x² + 2 + r = 3x⁵ + 3x³ + 2x² + x + 2
-x³ - 6x² + 2 + r = 3x³ + 2x² + x + 2
-6x² + 2 + r = 4x³ + 2x² + x + 2
2 + r = 4x³ + 8x² + x + 2
r = 4x³ + 8x² + x
Answer:
<h2>
$ 8.75 </h2><h2>
</h2>
Step-by-step explanation:
Samantha paid $26.25 for three books that all cost the same amount.
What was the cost of individual book?
<u> $26.25 for three books </u> = $ 8.75
3
therefore, the amount or each book cost $8.75
Answer: Angle DCE would be 12
Step-by-step explanation:
Assuming that angle BCD is right then just set up equation to equal to 90
4x+10+2x+8=90
then solve
6x+18+90
6x=72
x=12
