Answer:
180-1(2x-40)
180-1(2x)+(-1)(-40)
180+−2x+40
Combine Like Terms:
180+−2x+40=(−2x)+(180+40)
-2x+220

An expression in expanded form for the decimal that shows more than 0 hundredths is 19.31
<h3>How to write an expression in expanded form for the decimal that shows more than 0 hundredths.</h3>
The time is given as:
Time = 19.305
The hundredth in the above number is 0
So, to write an expression in expanded form for the decimal that shows more than 0 hundredths;
We simply approximate 19.305
So, we have:
Time = 19.31
Hence, an expression in expanded form for the decimal that shows more than 0 hundredths is 19.31

Answer:
The first. Ariel want to find the difference of a number and 13.
Problem: 2x^2+3x-9
For a polynomial of the form, ax^2+bx+c rewrite the middle term as the sum of two terms whose product a·c=2·-9=-18 and whose sum is b=3.
Factor 3 out of 3x
2x^2+3(x)-9
Rewrite 3 as -3 plus 6.
2x^2+(-3+6)x-9
Apply the distributive property
2x^2(-3x+6x)-9
Remove the parentheses
2x^2-3x+6x-9
Factor out the greatest common factor from each group
Group the first two terms and the last two terms
(2x^2-3x) (6x-9)
Factor out the greatest common factor in each group.
x(2x-3)+3(2x-3)
Factor the polynomial by factoring out the greatest common factor, 2x-3
(x+3) (2x-3). So, the quotient is 2x-3
