_______ perpendicular. ⊥
Hello!
26xy(x + 5)(y - 4) ÷ 13x(y - 4) =
= 2xy × (x + 5) × (y - 4)x × (y - 4) =
= 2x²y × (x + 5) × (y - 4) × (y - 4) =
= 2x²y × (x + 5) × (y - 4)² =
= 2 × [x × (y - 4)]² × y × (x + 5) =
= 2(xy - 4x)² × y × (x + 5) =
= (2xy + 10y) × (x²y² - 8x²y + 16x²) =
= 2x³y³ - 16x³y² + 32x³y + 10x²y³ - 80x²y² + 160x²y
Good luck! :)
Answer:
-2 and -10
Step-by-step explanation:
-2×-10=20
-10+-2=-12
Hope this helps! :)
Angles ACD and ACE are supplementary. They combine to form a straight angle which is 180 degrees. Let x be the measure of angle ACE.
----
(angle ACD) + (angle ACE) = 180
100 + x = 180
x = 180-100 .... subtract 100 from both sides
x = 80
<h3>angle ACE is 80 degrees</h3>
Answer:
half of 20 is 10
10 is your new radius so
10^2 = 100
100 x 3.14 = 314
Now we multiply by the height:
314 x 11 = 3,454 cm^3
