Simplify(7x^-2x+5)-(3x^2+4x+10)<br> show all steps
ad-work [718]
If we are looking to simplify two trinomials, it is easiest to put them on top of each other and subtract.

   7x²  - 2x  + 5                      7x² - 2x + 5
- (3x² + 4x + 10)                  -3x² - 4x - 10

4x² - 6x - 5

Find the value of x, question and choices attached above
Levart [38]

Answer:

<h2>E. 22</h2>

Step-by-step explanation:

<em>Look at the picture</em>.

The lines <em>l</em> and <em>m</em> are parallel, therefore alternate interior angles are congruent.

Therefore \beta=50^o

Supplementary angles add up to 180°.

Therefore

(5x-16)+\theta=180          <em>add 16 to both sides</em>

5x+\theta=196         <em>subtract 5x from both sides</em>

\theta=196-5x

We know: the sum of the triangle angle measures is 180°.

Therefore we have the equation:

50+2x+196-5x=180\\\\-3x+246=180\qquad\text{subtract 246 from both sides}\\\\-3x=-66\qquad\text{divide both sides by (-3)}\\\\x=22

Kris is setting up tables for an awards banquet. Each table seats 16 people. What is the fewest number of tables
oksian1 [2.3K]
Divide 132 by 16 to get 8.25 and you have to round up because you can’t fit 0.25 of people on a table.

Alex_Xolod [135]

Answer:

Step-by-step explanation:

Pythagoras theorem

a^2=b^2+c^2

(x-2)^2=9^2+(x+1)^2

x^2-4x+4=81+x^2+2x+1

Collect like terms

-4x-2x=82-4

-6x=78

x=-13
