Answer:
=25a6−36a4
Step-by-step explanation:
=(5a3+−6a2)(5a3+6a2)
=(5a3)(5a3)+(5a3)(6a2)+(−6a2)(5a3)+(−6a2)(6a2)
=25a6+30a5−30a5−36a4
=25a6−36a4
Answer:
see explanation
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius, here r = 9, thus
A = 4π × 9² = 4π × 81 = 324π ≈ 1017.9 units²
-- Carefully cut <em>each bar into 6 equal pieces</em>.
There are (5 x 6) = 30 pieces all together.
Each piece is 1/6 of a bar.
-- Each child gets 5 of the pieces.
That's the same as <em>5/6 of a whole bar</em>.
(6 children) x (5 pieces) = 30 pieces. It works out. yay !
Answer:
6 2/25 tons cement
Step-by-step explanation:
If cement mixer held 6 3/4 tons=6.75 tons
Mr. Folley used=0.67
After use cement are=6.75-0.67=6.08
So,
0.08=2/25
That's why answer is 6 2/25 tons
Y = X times 2 + 3 if that's what you're asking so y = 5x
Explanation:
2+3=5 so 5x bc x isn't a number
