zero product property
easy way
zero product
factor perfect square
m^2-3^2=0
(m-3)(m+3)=0
set each to zero
m-3=0
x=3
m+3=0
m=-3
m=-3 or 3
easy way
add 9 to both sides
m^2=9
sqrt both sides remember to take postive and negative roots
m=+/-3
m=-3 or 3
B is answer
Answer:
Cost of 11 cans of Dog food is $9.57
Step-by-step explanation:
Cost of 5 cans of dog food = $4.35
So to find out the cost of 11 cans of dog food at the same price, we need to calculate the price of 1 can of dog food.
<u>Calculation for finding out cost of 1 can of dog food</u>
The price $4.35 which is given is the price of 5 cans
So to find the cost of 1 can, we need to divide the given price by 5
5 Cans of dog food = $4.35
1 can of dog food = 4.35 ÷ 5
1 can of dog food = $0.87
<em><u>Now to find out the price of 11 cans, we will multiply the price of 1 can with 11</u></em>
Cost of 11 cans = 11 × $0.87
= $9.57
