Answer:
b
Step-by-step explanation:
sin θ=√(1-cos²θ)=√(1-9/25)=√(16/25)=4/5
sin 2θ=2sin θ × cos θ=2×3/5×4/5=24/25
You can do
70 x 6000
and
6000 x 70
=420000
Answer:
x = 2 or
x = -7
Step-by-step explanation:
(x - 2)(x + 7) = 0
x - 2 = 0
Add 2 to both sides
x - 2 + 2 = 2 + 0
x = 2
OR
x + 7 = 0
Subtract 7 from both sides
x + 7 - 7 = 0-7
x = -7
Therefore
x = 2 or
x = -7
Answer:
no, there is an infatuate amount of solutions
Step-by-step explanation:
1.2(2x-5)=2/5(2x-15)+1.6x
2.4x -6 = .8x -6 +1.6
2.4 -6 = 2.4-6
