Answer:

The radius is 9.0 units

Step-by-step explanation:

we know that

In the right triangle of the figure ABC

Applying the Pythagorean Theorem

$AC^2=AB^2+BC^2$

substitute the given values

$15^2=AB^2+12^2$

solve for AB

$AB^2=15^2-12^2\\AB^2=81\\AB=9\ units$

Remember the the side AB of right triangle represent the radius of the circle

therefore

The radius is 9.0 units

4(x+8)-2(x-7)=46 x=?

Scorpion4ik [409]

Answer:

x = 0/2

x = 0

Step-by-step explanation:

4(x+8)-2(x-7) = 46

Expanding the brackets

4x +32 - 2x +14 = 46

2x + 46 = 46

2x = 46-46

2x = 0

x = 0/2

x = 0

The length of a rectangle is 4 less than three times its width. The perimeter is 72 feet. What are the dimensions of the rectang

Liono4ka [1.6K]

Say width equals x.
Length = 3x - 4
Solve for x: 72 = 2(3x - 4) + 2x
72=6x-8+2x
80=8x
X=10
So width = 10
Length= 3(10) - 4 = 26

7x + 2y = 4

Vinil7 [7]

$7x + 2(x + 1) = 4 \\ 7x + 2x + 2 = 4 \\ 9x + 2 = 4 \\ 9x = 2 \\ x = \frac{2}{9} \\ \\ y = \frac{2}{9} + 1 = \frac{11}{9} \\ ( \frac{2}{9} \: \frac{11}{9} )$
