Answer:
x< -9
Step-by-step explanation:
9x-8x<-2-7
x< -9
A
X-54=20
+54. +54
You add 54 to both sides
Then you end up with
X = 74
So the letter is on page 74.
Answer:
Im pretty sure its c
Step-by-step explanation:
2x^2+20x=-38 divide both sides by 2
x^2+10x=-19, halve the linear coefficient, square it, than add that value to both sides of the equation, in this case add (10/2)^2=25...
x^2+10x+25=6 now the left side is a perfect square
(x+5)^2=6 take the square root of both sides
x+5=±√6 subtract 5 from both sides
x=-5±√6 (so answer c.)
