Answer:

$x=55$

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of $2x+6$ corresponds with the angle marked as $x+9$ . Therefore, its measure must also be $x+9$ .

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

$2x+6+x+9=180$

Combine like terms:

$3x+15=180$

Subtract 15 from both sides:

$3x=165$

Divide both sides by 3:

$x=\frac{165}{3}=\boxed{55}$

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters. The radius of sphere A is multiplied by

Tamiku [17]

Answer:

7/8

Step-by-step explanation:

Sphere A has a radius of 24 centimeters, and sphere B has a diameter of 42 centimeters.

WE need find which factor is multiplied with radius of sphere A to produce the radius of sphere B

Diameter of sphere B is 42

Radius = diameter /2

Radius = 42/2= 21

Radius of sphere B = 21

RAdius of sphere A times x= radius of sphere B

24 * x= 21

Divide by 24 on both sides

x= 21/ 24

divide top and bottom by 3

x= 7/ 8

Evaluate the expression when x=-5 <br> X^2 + 6x-9

d1i1m1o1n [39]

The value of the function f(x) = x² + 6x - 9 when x = -5 is -14.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Given that:

f(x) = x² + 6x - 9

When x = -5:

f(-5) = (-5)² + 6(-5) - 9 = -14

The value of the function f(x) = x² + 6x - 9 when x = -5 is -14.
