Answer:
b. -x^2 + 50 = 25
c. |2x| = 10
d. x < 0
e. 2x < 10
Step-by-step explanation:
x = -5
-(-5)² + 50
-25 + 50 = 25
|2(-5)| = |-10| = 10
-5 < 0
2(-5) = -10 < 10
1.17-3.99a
You can only combine like terms and 1.17 is not a like term to -0.07a and -3.92a
So you can only combine the like terms
Heres how you do it
10+2 =12 which means 72
D
X 90 z 90 y 90
