The solution of the equation 9² + 12² = c² will be 15 and negative 15.

A designation of amounts to the unknown parameters that establish the equals in the formula is referred to as a result.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The equation is given below.

9² + 12² = c²

Simplify the equation, then the value of the variable c will be

c² = 81 + 144

c² = 225

c = ±√225

c = ±√(15)²

c = ± 15

Thus, the solution of the equation 9² + 12² = c² will be 15 and negative 15.

= 5r + 3r - 8r

= 8r - 8r

= 0

Answer:

0

Answer:

2, 10%, 15, 42

Step-by-step explanation:

18 / 9 = 2

Total number of students = 60

6 / 60 = 1/10 or 10%

1/3 ride the bus, so a sample of 45 would give 15

7/60 ride a bike so multiply by 360 = 42

Answer:

C. 84

Step-by-step explanation:

To make it easier to find the total area, you should break the shape into two parts, a triangle and a rectangle.

Step 1:

To find the rectangle area we now we have to multiply l * w

In this case, the length is 12 and the width is 4 so 12*4 = 48

Step 2:

To find the area of the triangle you have to do the formula A = 1/2bh where b is the base 12, and h is the height (10-4) 6. So 6*12 = 72 and 72/2 is 36

Step 3:

Last you need to add the area of both the rectangle and the triangle to get the total area of 84 sq meters

Answer:Let's start with the underlying fact. Multiplication simply is not repeated addition, and telling young pupils it is inevitably leads to problems when they subsequently learn that it is not. Multiplication of natural numbers certainly gives the same result as repeated addition, but that does not make it the same.

Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. ... It is also known as the slope and gives the rate of change of the dependent variable.

Answer:

Use these variables to make an equation-

y is the total amount.

$50 is where you start charging(y-intercept, variable b).

x is how many visits Marsha made.

The equation can be in slope-intercept form (y=mx+b)-

$144=$2x+50

Solve for x using inverse operations.

Subtract 50 from both sides-

144-50=2x+50-50

94=2x

Divide 2 from both sides-

94/2=2/2

x=47
