Answer:
8sin(x)cos³(x)
Step-by-step explanation:
sin(4x) +2 sin(2x) = 2sin(2x)*cos(2x) + 2sin(2x) = 2sin(2x)(cos2x + 1)=
= 2sin(2x)(cos²x - sin²x + cos²x + sin²x)=²2sin(2x)*(2cos²x)=
= 4*2sin(x)*cos(x)*cos²(x)= 8sin(x)cos³(x)
Answer:
50 degrees.
Step-by-step explanation:
The angles of a triangle will always add up to be 180, so add and subtract to find the missing value. :)
Answer:
pls give brainlist
Step-by-step explanation:
a. 
50 x 9 = 450. A=450
b. I can scale the unit rate of the area given above and largen the area of the map. Ex. 
=
<---(scaled by 2)
Then we can enlarge it however we want so,
= 
<--(scaled by 2 once more)
If the statement above is true then we can scale times 4.
= 
<---(scaled by 4)
A= 
all i can give u at the moment , if u go on M a t h w a y it can help
The value of x (if it’s a side length) should be 6 inches
