Answer:

x = 3

Step-by-step explanation:

\frac{80}{120} = \frac{2}{x}

Simplify, divide the numerator and denominator by the same number

\frac{80}{120}\\

÷ 40

\frac{2}{3}

\frac{2}{3} = \frac{2}{x}

Cross products

2x = 2 *3\\2x = 6\\/2    /2\\\\x = 3

Find the Area Of each circle.
Levart [38]

The area of the circle A and B is 86.54 inches and 124.62 mm

According to the statement

we have given that the radius of the circle A and b and we have to find the area of the given circle.

So, we know that the

The area enclosed by a circle of radius r is πr².

So, For area of the circle

For condition A :

diameter = 10.5 inches

then radius = 5.25

Area = πr²

Area = 3.14*27.56

Area = 86.54 inches

Now, For condition B :

radius = 6.3 mm

Area = πr²

Area = 3.14*39.69

Area = 124.62mm

So, The area of the circle A and B is 86.54 inches and 124.62 mm

Help me out please, im only typing this much because its making me...
Genrish500 [490]

Answer:

B.x^{2} +2x-8

Step-by-step explanation:

Here the best method to solve is by substituting the end values of the set in each option , otherwise it will a time consuming problem.

Now substitute x=-4 in all the options

A.x^{2} -2x-8

16+8-8=16>0

so out of option A and C option C is correct.

B.x^{2} +2x-8

16-8-8=0 which means for the values of x>-4 x^{2} +2x-8is less than 0

Now substitute x=2 in all the options

A.x^{2} -2x-8

4-4-8=-8<0 . so option A and C both are incorrect.

B.x^{2} +2x-8

4+4-8=0 which means for the values of x<2 x^{2} +2x-8 is less than 0

Therefore the correct option is B
