Answer:
=14x² −3x −1
Step-by-step explanation:
simplifying step-by-step.
9x2+5x2+5x−3−(8x−2)
Distribute the Negative Sign:
=9x2+5x2+5x−3+−1(8x−2)
=9x2+5x2+5x+−3+−1(8x)+(−1)(−2)
=9x2+5x2+5x+−3+−8x+2
Combine Like Terms:
=9x2+5x2+5x+−3+−8x+2
=(9x2+5x2)+(5x+−8x)+(−3+2)
=14x2+−3x+−1
Answer:
=14x2−3x−1
Answer: $391.08 would be how much he really has in his register. I may be a little off though.
Answer: 4 1/2 and 27
Step-by-step explanation:
Divide the restocking fee by the price of the item:
12/200 = 0.06
9/150 = 0.06
Multiply by 100 to get the percent:
0.06 x 100 = 6%
Answer: 6%
Angles ABC and CBD are complementary - they add up to 90°. This means
(4x + 52°) + (8x - 10°) = 90°
Solve for x :
12x + 42° = 90°
12x = 48°
x = 4°
It follows that angle CBD has measure
4 • 4° + 52° = 16° + 52° = 68°
