Answer:
-50
Step-by-step explanation:
X^2+2x= -8
x^2+2x+1= -8+1
(x+1)^2= -8+1
(x+1)^2=-7
x+1= √-7
The answer is No Solution because the root of a negative number is not a real number.
Answer:
92 more miles (D)
Step-by-step explanation:
I believe the answer is 92 more miles (d). So we know that Mr Klein is driving at a steady 60 miles per hour for 42 minutes. There are 60 minutes in an hour, so every minute they've driven a mile. Therefore, in 42 minutes, they've driven 42 hours. And then 134 - 42 is equal to 92, which is your final answer.
Hope this helped!! :D
Answer:
4x² + 18
Step-by-step explanation:
note that (c ○ d )(x) = c(d(x))
To evaluate substitute x = d(x) into c(x), that is
c(d(x))
= c(x² + 5)
= 4(x² + 5) - 2
= 4x² + 20 - 2
= 4x² + 18
237 is the answer because 200+30+7 if you add that up together you will get 237
