Answer:

$\frac{8}{15}$

Step-by-step explanation:

1) use this rule: $\frac{a}{b}$ × $\frac{c}{d} =\frac{ac}{bd}$

$\frac{4*2}{5*3}$

2) simplify 4 * 2 to 8

$\frac{8}{5*3}$

3) simplify 5 * 3 to 15

$\frac{8}{15}$

Find all solutions to the equation.

Bess [88]

If the equation is

$7\sin^2x-14\sin x+2=-5$

then rewrite the equation as

$7\sin^2x-14\sin x+7=0$

Divide boths sides by 7:

$\sin^2x-2\sin x+1=0$

Since $x^2-2x+1=(x-1)^2$ , we can factorize this as

$(\sin x-1)^2=0$

Now solve for x :

$\sin x-1=0$

$\sin x=1$

$\implies\boxed{x=\dfrac\pi2+2n\pi}$

where n is any integer.

If you meant sin(2x) instead, I'm not sure there's a simple way to get a solution...

GCF of 4x^2y^2, 3xy^4, and 2xy^2

allsm [11]

The greatest common factor would be xy^2 because these are the only factors that they all have in common. The second term only has 1 x, so only 1 x is part of the gcf.

The 1st and 3rd terms each have y^2 therefore making it part of the gcf as well.
