- -16x +17
Step-by-step explanation:
1 . (4x² - 9x + 16) + (7 + 9x² - 10x)
4x² - 9x + 16 + 7 + 9x² - 10x
13x² - 19x + 23
2 . (-2x + 6) - (14x - 11)
-2x + 6 - 14x + 11
-16x +17
There aren't any answer options so I will just simplify the expression:
10(2p+q)
20p+10q

the explanation is in the picture
please like and Mark as brainliest
87 / 114 = x / 9918....87 people to 114 = x people to 9918
cross multiply
(114)9x) = (87)(9918)
114x = 862866
x = 862866/114
x = 7569 <===
