Answer:
x < -16
Step-by-step explanation:
Any number less than -16 will work. So x could equal -12309 or -109 or -50 and even -19234870237503 would work.
To find which inequalities of x work, simply subtract 19 on both sides.

Il me semble que le triangle MNP devrait ressembler à celui que j’ai attaché.
Les triangles MNP et MQR sont similaires, les côtés correspondants sont donc proportionnels:




Did you mean :
f(x) = x² - 2x, find x = -3
f(-3) = (-3)² - 2(-3)
f(-3) = 9 + 6
f(-3) = 15
Answer:
She now has 84 nickles. :)
Step-by-step explanation:
40+44=84
1/4a + 1/3a +8 =22
1st step add like terms:
1/4a +1/3a = 3/12a +4/12a = 7/12a
7/12a +8 =22
2nd step subtract 8 from each side:
7/12a = 14
3rd step divide both sides by 7/12 to get a:
a = 14 / 7/12
a = 24
