Hello!
<u><em>Explanation: Addition property of equality is adding the same number to both sides of an equation does not change the equation.</em></u>
<u><em>a+c=b+c</em></u>
<u><em>First, add by 23 both sides of an equation.</em></u>
<u><em>y-23+23=-5+23</em></u>
<u><em>And then, simplify.</em></u>
<u><em>23-5=18</em></u>
<u><em>It changes negative to positive sign.*</em></u>
<u><em>Final answer is y=18</em></u>
<u><em>Hope this helps!</em></u>
<u><em>Thanks!</em></u>
<u><em>Have a great day!</em></u>
Answer:
A.-12x^2-5x-102
Step-by-step explanation:
We are given a polynomial of degree 2 where terms are not grouped and simplified.
We have
-21x^2+22x^2-13x^2-10x+5x-102
To get this in proper form we have to group the like terms first
x^2 term = -21x^2+22x^2-13x^2 = x^2 (-21+22-13)
= x^2(-34+22) = -12x^2
x terms are -10x+5x = x(-10+5) = -5x
Constant term is only one = -102
Hence the polynomial in simplified form is
-12x^2-5x-102
