Question 1: To find volume the formula is Length× Width × height
So it would be 2 1/2× 6 × 3 1/2= 5 1/2
So the volume is 5 1/2
Question 2: You have to multiply 6 × 4 = 24
2 areas because there isnt an equal amount of elm trees and oak trees to be planted
Answer:
Step-by-step explanation:
Since the expressions are multiplied, for the product to equal zero, one term or another has to equal 0 because 0 times anything is zero.
(10-x)(3x-9)=0 when
10-x=0, x=10
3x-9=0, x=9/3=3
So there are two solutions when x=3 and x=10
Answer:

Step-by-step explanation:
The given equation is A=4 πr².
We need to solve the above equation for r².
We have,
A=4πr²
Dividing both sides by 4π, we get :

Hence, the value of r² is equal to
.
6 - 10x = 16
-10x = 10, x = -1
5(-1) = -5
The answer is d
