Answer:
fog(x)= -4x+11
Step-by-step explanation:
Here,
f(x) = 2x - 3
g(x) = 2x - 4x +7 = -2x+7
fog(x)= f(-2x+7)
= 2(-2x+7)-3
= -4x+14-3
= -4x+11
-5c^2-3c+4 This polynomial is in standard form, now, and the leading coefficient is 5, because it is the coefficient of the first term. Degree is 2, due to -5c^2.
Answer:
201.06
Step-by-step explanation:
You can plug in the 8 from the circle into the equation to find the area.
Answer: 12 sqrt(5)
Explanation:
First simplify:
= Sqrt(45)
= sqrt(9*5) sqrt of 9 is 3 so bring out 3
= 3sqrt(5)
= 2sqrt(20)
= 2sqrt(4*5) sqrt of 4 is 2 so bring that out and multiply it by 2
= 4sqrt(5)
= 5 sqrt(5) is already simplified
= 3sqrt(5) + 4 sqrt(5) + 5sqrt(5)
= 12 sqrt(5)
Answer:
L=8
Step-by-step explanation:
area of a rectangle = length x width
given:
area= 20 square units
width =2.5 units
find the length by substituting :
20=2.5 x L
L= 20/2.5=8
that's it :)
