Answer:
70
Step-by-step explanation:
the red lines mean the two sides are equal
so its an isosceles triangle meaning the two angles other than the 40° one are equal
the inner angles of a triangle must add up to 180
so 180-40 = 2x
140 = 2x
x = 140/2 = 70
We have to get the y alone. So we'll subtract 3x on both sides.
Our new expression is y<-3x+8

sorry if this doesn't help
Answer:
6
Step-by-step explanation:
y + 1
= 7
y + 
= 
y = 40/6 = 20/3 = 6
The answer is 2 first you add then multiple
This just wants the derivative which you can solve for.
You can do this using a negative expononet or using ...the rational rule forget its name*.... you shoudl get 9000/(t+12)^2
*Quotient rule
