Formula of the Volume of a Pyramid is:

×Area of Base×Height of pyramid
V=

×3×4 (area of base=3 ft²)
V=4 ft³

and 3 cancels out.
Answer:
Option (3)
Step-by-step explanation:
We have to divide polynomial given as (x³ - 21x² + 147x - 343) by (x - 7) by synthetic division.
7 | 1 -21 147 -343
<u> ↓ 7 -98 343 </u>
1 -14 49 0
Therefore, quotient is (x² - 14x + 49) and the remainder will be 0.
Option (3) will be the answer.
Step-by-step explanation:

Answer:
y=3 or y-3=0
Step-by-step explanation:
-2y=-6
-2y÷(-2)=-6÷(-2)
y=-6÷(-2)
y=-6÷2
y=3
or
-2y=-6
-2y+6=0
-y+3=0
y-3=0
Answer:
b = (2A)/h
Step-by-step explanation:
With area formula for triangle: A = (1/2)*b*h
Solve for b
2*A = 2*(1/2)*b*h
2A = bh
2A / h = b
