240-15m = 200-5m
we need to get the terms with the m on one side of the equations and the other terms on the other side:
240-200 = -5m+15m
40 = 10m
m = 40/10
m = 4
Answer:
steps below
Step-by-step explanation:
Are you going to solve the value of A or just a proof the equation
cos 2A = cos² A - sin² A
2cos²A-cos2A-1 = 2cos²A - (cos² A - sin² A) - 1 = cos² A + sin² A - 1
2cos²A-cos2A-1 = 1 - 1 = 0
A: 90° or 270° or 450° .....
Answer:
W = 24
Step-by-step explanation:
Is means equals and of means multiply
W = 48% * 50
Change percent to a decimal
W = .48 * 50
W = 24
Answer:
√(137)
Step-by-step explanation:
First, you will need to find the other side length.....then you can use the Pythagorean Theorem to find the diagonal:
L x W = 44
4 x W = 44
W =11
Now the Pythag, Theorem:
diagonal^2 = 4^2 + 11^2
d^2 = 16+121
d^2 = 137
d = √(137)
