A ) equation would be X = Z / Y
B ) if X = 9 ------------> Y = 1/7
X = 21 ----------> Y = ?
21*1/7 = 21/7 , 21/7÷9 = 21*9/7 = 27
so Y equal 27
Answer:
355.2
Step-by-step explanation:
Given:
Four percent of Jennie's skin cells were burned
Total skin cells having Jennie = 3.7 x 10^10
=
To find:
How man skin cells were not burned ?
Solution:
Total skin cells having Jennie = 370
Percent of Jennie's skin cells were burned = 4%
Skin cells burned from a fire =
=
=
Remaining skin cells which not burned = 370 - 14.8 = 355.2
Therefore, 355.2 skin cells were not burned.
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).
