7.21

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle.

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

12 ^2 + x^2 = 14^2

144 + x^2 = 196

Subtract 144 from each side

144-144 +x^2 = 196-144

x^2 = 52

Take the square root of each side

sqrt(x^2) = sqrt(52)

x =7.211102551

Rounding to the nearest hundredth

x = 7.21

7.21

Step-by-step explanation:

A^2+b^2=c^2 so 12^2+x^2=14^2 so 144+x^2=196 so 52=x^2 sqrt of 52 is around 7.21

3)5x-4y=-3

6x+4y=14

Step-by-step explanation:

The system of equations is given

5x-4y=-3

3x+2y=7

Multiplying both sides of the lower equation by 2, we get

6x + 4y = 14

That means your answer 3)

1)

The factors of 9 are: 1, 3, 9

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 3.

2)

The factors of 16 are: 1, 2, 4, 8, 16

The factors of 28 are: 1, 2, 4, 7, 14, 28

Then the greatest common factor is 4.

3)

The factors of 50 are: 1, 2, 5, 10, 25, 50

The factors of 75 are: 1, 3, 5, 15, 25, 75

Then the greatest common factor is 25.
