Answer:

17/6

Step-by-step explanation:

We know that,

perimeter of rectangle=2(l+b)

or,50=2(2x+x+4)

or,50=2(3x+4)

or,25=6x+8

or,17=6x

•x=17/6

P(A) = 0.7
P(B) = 0.8

P(A∩B) ⇒ When both event happens
P(A∩B) = 0.7 x 0.8 = 0.56

N = 14.4

so it would be "B"

24 x 5.85 = 140.4

9.75 x n = 9.75n

140.4/9.75 = 14.4
n=14.4

Idk how to explain my work :/ help ?

The total arc length around a circle is 360 degrees. So, these 3 arc with expressions given will all add up to 360.

(-2 + 8x) + (10x + 10) + (10x - 12) = 360

28x - 4 = 360

28x = 364

x = 13

Now that we know the value of x, we can plug that value into the expression for arc LM and solve for the measure.

LM = 10x - 12

LM = 10(13) - 12

LM = 118 degrees

Hope this helps! :)

Answer:

$\sqrt[4]{x^5}$

Step-by-step explanation:

A fraction exponent converts into a radical. The denominator is the index of the radical (farthest left number) and the numerator is the exponent of the base inside (the farthest right number). The base of the fraction exponent is the base number in green. To write this expression, simply the exponents into one exponent and one base.

$x^{\frac{3}{4}}x^{\frac{1}{2} } =x^{\frac{3}{4}}x^{\frac{2}{4} } =x^{\frac{3+2}{4}} =x^{\frac{5}{4}}$
