Hi there!
a. 8x^2 - 1
(x^2 - 4x + 5) + (7x^2 + 4x - 6)
= x^2 + 7x^2 - 4x + 4x - 1
= 8x^2 - 1
b. 5x^2 + 7x - 7
(7x^2 + 4x - 6) - (2x^2 - 3x + 1)
= 7x^2 + 4x - 6 - 2x^2 + 3x - 1
= 7x^2 - 2x^2 + 4x + 3x - 6 - 1
= 5x^2 + 7x -7
Hope this helps!
Answer:
The answer to your question is Volume = 12735.06 cm³
Step-by-step explanation:
Data
a = 11.26 cm
s = 13 cm
h = 29 cm
Formula
V = BH
Process
1.- Calculate the area of the base
Area = B = Pa/2
P = Perimeter
P = 6(13)
P = 78 cm
Area = (78)(11.26)/2
= 878.28/2
= 439.14 cm²
2.- Calculate the volume
Volume = BH
= (439.14)(29)
= 12735.06 cm³
Answer:
There kind of needs to be more information. We don't have any other information other than the backstory. You're gonna need to elaborate.

Answer:
Step-by-step explanation:
L=3(5280)/(2(380+250))
L=15840/1260
L=12.57
So to walk three miles one must walk around the garden 12.57 times.
<span>1C. 5^3 = 125 mL
2A. 30^3 = 27,000 mL = 27 L
3D. 75 mm is 7.5 cm, so we do: 7.5^3 = 421.875 mL = 0.421875 L =~ 0.422 L
Note:
1 mL = 1 cm^3
1 L = 1,000 mL
10 mm = 1 cm</span>
