A) 17.69
You just substitute the h for 3
Answer:
Option B. 
Step-by-step explanation:
we know that
The volume of the square pyramid is equal to

where
b is the length side of the square base
H is the height of the pyramid
we have


substitute


Conver to y=mx+b form
m=slope
b=yintercept
y-12=3x
add 12 both sides
y=3x+12
m=3
b=12
gradient aka slope=3
yintercept=12
Answer:
Step 2 involved distributive property and the value of y is equal to 8.
Step-by-step explanation:
In step 2, there has been an error in applying the Distributive Property correctly.
Distributive Property- a(b+c)
= a x b + a x c
Step 2: 
Step 3:
Step 4: 
y=8
Here you go. I hope you understand. Ask if you don't.
