So far, there is no units we can see becaus we have no context what this is trying to find
so
use the distributive property which goes like this: a(b+c)=ab+ac
so
first distribute
6(60-r)=6(60)+6(-r)=360-6r
now we have
15r+360-6r=
15r-6r+360=
9r+360
there are no units associated with the expression
Answer:
37in.^2
Step-by-step explanation:
So if the triangles at the top have a hypotenuse of 5, and a length of 4, then doing reverse Pythagorean theorem, you find out that the width is 3.. so reverse of that for this problem would be and if we plug it in, we get 25 -16=9 and the square root of 9 is 3. so if we find the are of the triangle, 3*4*1/2=6 and there are 2 triangles so 12 for both triangles. The square is 5*4=20. and the smaller triangles on the side are 1*5*1/2=2.5, and there are 2 traingles so 2.5*2= 5. So 5+20+12=37. You can do this on most calculators, and please put my answer as the brainliest.✌
At the risk of piling on after correct answers have already been given, I’ll offer another way to address this problem. Recall that, if
θ
is real, cos()=Re()
cos
(

)
=
R
e
(

. So, with
A
and
B
real,
(+)+(−)=(+−)=2cos()

Finally,
cos(+)+cos(−)=Re((+)+(−))=Re(2cos())

Answer:
-1 , |-2| , 3 , 4 , |5|
Step-by-step explanation:
upright bars | | mean absolute value
upright bars | | make the number inside them
positive
|-2| = 2
|5| = 5
4, |-2|,3,|5|,-1
-1 , |-2| , 3 , 4 , |5|
