Answer:
2x+2
Step-by-step explanation:
(2x^2 + 10x + 8)
----------------------
(x + 4)
Factor the numerator
2 (x^2 + 5x + 4)
----------------------
(x + 4)
2 (x+4)(x+1)
----------------------
(x + 4)
Cancel the common factors
2 (x+1)
Distribute
2x+2
Answer:
A.
Step-by-step explanation:
Given:-
Actual size of billboard,
Width(w)=2.61 inches
Length(l)=6.14 inches
Now,
To create a billboard in scale 1 inch to 7.81 feet,
this means,
1 inch=7.81 feet --------------(as per scale)
So,
2.61 inches=2.617.81
2.61 inches=20.38 feet (Width)
6.14 inches=6.147.81
6.14 inches=47.95 feet (Length)
Now the area of billboard as per scale is:
Therefore billboard nearest area is A. 977
Answer:
Step-by-step explanation:
First you mean: cos2x = (cosx)^2
For A. 2(cosx)^2-1 = 1 - 2(sinx)^2
we have (cosx)^2 + (sinx)^2 = 1, This is an identity
For B. secx cscx(tanx + cotx) = sec2x + csc2x
So the B is an identity.
For C, I do not understand the ?
For D secax is what?
|x|-6=4
|x|=4+6
|x|=10
Therefore, x=-10 and x=10.
