Find x (x+13)(x-7)=0

Mathematics
1 answer:
alex41 [277]3 years ago
7 0

So for this, we will be applying the <u>zero product property</u>, which is <u>"if a x b = 0, then either a = 0 or b = 0 or both a and b = 0"</u>. In this case, a = x + 13 and b = x - 7. Solve them separately:

x+13=0\\ x=-13\\ \\ x-7=0\\ x=7

<u>Your answer is x = -13 and 7.</u>

igor_vitrenko [27]

The number is 6400.

We have given that,

divided 80 by my number, and then added 13.

<h3>What is the expression?</h3>

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Suppose the number is x

\frac{x}{80}+13=93

Subtract  13  from both sides

\frac{x}{80}+13-13=93-13

\frac{x}{80}=80

Multiply both sides by 80

\\\frac{80x}{80}=80\cdot \:80

x=6400

Therefore the number is 6400.

Find the value of x PLEASE EXPLAIN
Wewaii [24]

Answer:

x = 57, x = 111

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

x + 67 + 56 = 180

x + 123 = 180 ( subtract 123 from both sides )

x = 57

---------------------------------------------------------------------

Similarly

x + 47 + 22 = 180

x + 69 = 180 ( subtract 69 from both sides )

x = 111
