1. False 2.True 3.20 4.13 5.-23 6. True 7. should be false because domain is a range of values and y- value is just one. 8.True
Answer:188
Step-by-step explanation:
u have to add all the side which is 46+46+13+13=188
Answer:
35 + 5x= 100 -8x =
Step-by-step explanation:
35 +5x =100 -8 x
5x + 8x = 100 -35
13x = 65
x = 13/65
x =5
10|5n-5|=50 divide both sides by 10
|5n-5|=5 square both sides:
25n^2-50n+25=25 subtract 25 from both sides
25n^2-50n=0 factor...
25n(n-2)=0
So n=0 and 2
The correct factor is (x - 2) and (x + 1).
<h2>Quadratic equation</h2>
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
Given
x² - x - 2 = 0 is a quadratic equation.
<h3>To find </h3>
The factor of the given equation.
<h3>How to find the factor of the given equation?</h3>
x² - x - 2 = 0 is a quadratic equation.
According to factorization,
x² - x - 2 = 0
x² - 2x + x - 2 = 0
x(x - 2) +1 (x - 2) = 0
( x - 2 ) ( x + 1 ) = 0
Thus the correct factor is (x - 2) and (x + 1).
