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
I believe it’s 12000 because 30x50=1500 1500x2=3000 now 3000x4=12000
Answer:
Too much
Step-by-step explanation:
I did the math myself
I’m guessing that x is the angle on the right that isn’t shown?
Anyways if that’s the case then:
We know that the sum of all the angles of a triangle add up to 180 degrees.
In this triangle we know that one angle is 55 degrees and the other is 90 degrees, so to find the last angle we do the sum of all the angles and we remove the 2 angles:
180- (55+90)= 35 degrees.
x= 35 degrees
Your answer would be y= 6x + 19
You get rid of the variable on the left side by adding it to both sides giving you y = 6x + 19
Hope it helps
