Answer:

13 hearts, plus 3 other queens- so 16 out of 52, simplified 4 out of 13.

x = 1

Answer:

$m\angle XVW = 100\degree$

Step-by-step explanation:

In the first figure, FP is the bisector of $\angle DFE$

$\therefore m\angle 1 = m\angle 2\\\therefore 44x + 1 = 46x - 1\\\therefore 1 + 1 = 46x - 44x\\\therefore 2 = 2x\\\therefore \frac{2}{2} = x \\\huge \red {\boxed {\therefore x = 1}}$

In the second figure, VP is the bisector of $\angle XVW$

$\therefore m\angle 1 = m\angle 2\\\therefore 12x + 2 = 11x +6\\\therefore 12x - 11x = 6 - 2\\\therefore x = 4\\\because m\angle XVW = m\angle1 + m\angle 2\\\therefore m\angle XVW = 12x + 2 + 11x +6\\\therefore m\angle XVW = 23x + 8\\\therefore m\angle XVW = 23\times 4+ 8\\\therefore m\angle XVW = 92+ 8\\\huge \purple {\boxed {\therefore m\angle XVW = 100\degree}} \\$

Solve!!!!! PLEASE HELP!!! MKE BRAINLIEST!<br> 2x^2 - 28 = x^2 + 15<br> What is the answer!

padilas [110]

Answer:

x = ± sqrt(43)

Step-by-step explanation:

2x^2 - 28 = x^2 + 15

Subtract x^2 from each side

2x^2-x^2 - 28 = x^2-x^2 + 15

x^2 -28 = 15

Add 28 to each side

x^2 - 28 +28= 15+28

x^2 = 43

Take the square root of each side

sqrt(x^2) = ± sqrt(43)

x = ± sqrt(43)
