Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : -7n = 0
Multiply both sides of the equation by (-1) : 7n = 0
Divide both sides of the equation by 7:
n = 0
Solving a Single Variable Equation:
3.3 Solve : n-7 = 0
Add 7 to both sides of the equation :
n = 7
This is what i got! if i’m wrong i’m so sorry
but i tried. have a amazing day☺️☺️
Answer:
134
Step-by-step explanation:
If this is right can I get brainliest?
4s + 5 = 19
First, subtract 5 from both sides. / Your problem should look like: 4s = 19 - 5.
Second, simplify 19 - 5 to 14. / Your problem should look like: 4s = 14.
Third, divide both sides by 4. / Your problem should look like: s =
.
Fourth, simplify
to
. / Your problem should look like: s =
which is the answer.
Answer:
The area increases by 6 square units.
Step-by-step explanation:
The formula for the area of a triangle is base times height divided by two.
So, first solve 3 times 4 divided by 2.
Simplify 4 and 2 and you get 3 times 2 which = 6
Then Mark doubles it right?
So do 6 times 2 and you get 12
The first answer is 6, so it increased by 6.
I hope this answer helped. Sorry if I was wrong.

We need to find 
.
represents, the element of third row and third column.
We would go third row that has elements 2 7 16 and
third column has elements -9 6.2 16.
We can see that element of third row and third column is 16.
<h3>Therefore, correct option is fourth option 16 in the given options.</h3>
