<h3>Given :</h3>

★ (9x² - 8x - 3) + (2x + 8)

We have to simply it.

⭆ 9x² - 8x - 3 + 2x + 8

⭆ 9x² - <u>8x + 2x</u> - <u>3 + 8</u>

⭆ <u>9x² - 6x + 5</u>

∴ (C) is the correct answer.

∠EFG and ∠LMN are supplementary angles, m∠EFG=(3x+17)º, and m∠LMN=(12x−5)º.
Ira Lisetskai [31]

Answer:

EFG = 50.6, LMN = 129.4

Step-by-step explanation:

ok so s supplementary angles mean, their angles will always add upto 180. for example if one angle is 100° then the other will be 80°.

to find the angles first we need to solve for x.

we know EFG + LMN = 180 because its supplementary.

that's is (3x+17) + (12x-5) = 180.

we now solve for x;

15x+12 = 180

15x = 168, x= 168/15 = 11.2

now that we know x we can put this value in the corresponding equation of EFG and LMN to find the angles.

EFG = 3x11.2 + 17 = 50.6

LMN = 12x11.2 - 5 = 129.4
