This would be the difference of perfect squares.
x^2 - 9
(x - 3) (x + 3)
Answer:
By knowing the formulas for the volume of the solids.
Step-by-step explanation:
To find it out, you need to know the formula for the solids shown such as the cone and the cylinder. The formula for the cone is 1/3hπr². The formula for the cylinder is hπr².
If you were asking for the answers,
Cone:
The radius for the cone is 12 inches.
Cylinder:
The height for the cylinder is 3.8 inches.
Answer:
6
Step-by-step explanation:
<u>Area of sq:</u>
A = bh
A = (2)(2)
A = 4
<u>Area of triangle:</u>
A = 1/2bh
A = 1/2(2)(2)
A = 2
<u>Combined:</u>
4 + 2 = 6
Answer:
x < -7
Step-by-step explanation:
2x + 9 = 8
Subtract 9 from each side :
2x = -1
Divide each side by 2 :
x = - 1/2
