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

What is the solution to the equation?

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.

Find the total area for the following composite shape.

A.48 sq m
B.36 sq m
C.84 sq m
D.64 sq m

Answers

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

Have a good day!!!

A health club charges a $50 initial fee plus $2 for each visit. Moselle has spent a total of $144 at the health club this year . Use an equation to find how many visits she has made

Answers

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

Moselle made 47 visits to the health club.

You know that multiplication can also be expressed as repeated addition. Why is it more difficult to use repeated addition when multiplying two mixed numbers than it is to use repeated addition when you are multiplying a mixed number by a whole number?

Answers

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.
