A) if they were the same function, they would have identical graphs ⇒ it's not A
B) it's flipped vertically, but it's not moved ⇒it's not B
C) it's flipped vertically, not horizontally ⇒ it's not C
So it must be D)
Volume is given by:
V=(base area)×(height)
base area=bh
where:
b=base=8.5 cm
h=height= 4 cm
thus
base area=8.5×4=34 cm²
Thus the volume will be:
V=34×14
V=476 cm³

Step-by-step explanation: since 70 in 20 is 1/3 multiply 70x3 and there´s your answer
Step-by-step explanation:
The formula of a volume of a pyramid:
B - base area
H - height
H - height of pyramids
Pyramid A:
Pyramid B:
The volume of the pyramid A is twice as large as the volume of the pyramid B.
The new height of pyramid B: 2H
The new volume:
The volume of the pyramid A is equal to the volume of the pyramid B.
Hello there!
A C method : you multiply the A and C -> find the factors of AC that can add up to B. (a² + bx + c)
15a² + 14a - 8
you multiply 15 and -8 = -120
Find the two factors of -120 that adds up to 14.
We could used 20 and -6.
So we can split the original equation to this:
15a² + 20a - 6a - 8
Now, we use grouping method.
Let's group 15a² + 20a and -6a - 8.
15a² + 20a can be factored like this :
5a(3a + 4)
-6a - 8 can be factored like this :
-2(3a + 4)
So it is 5a(3a + 4) × -2(3a + 4)
We can simplify this into this :
(5a - 2)(3a + 4)
So your final answer is (5a - 2)(3a + 4).
Hope this helped! :)
