To find the area of a rectangle the formula is:

Area = length * height

A = L * H

In this case:

L = 3x

H = 2x

^^^In-put these values into the equation given above

A = 3x * 2x

Now you must multiply them together.

When multiplying numbers with variable(s) you multiply the number portion normally ( 3 * 2 = 6).

Multiplying variables is slightly different. The matching variables (x and x) will become one "x" and have an exponent attached to the x.

What will the exponent be? If a variable has no visible exponent it can be assumed that it has an exponent of 1. When multiplying variables the exponents on each variable will be <em>sumed </em>together and attached to the final variable:

x^{1} *x^{1} = x^{1+1} = x²

Now combine the product of the numbers with the product of the variables:

Area = 6x²

Hope this helped!

A circle has an area of 78.5 square inches what is the radius of the circle
Alinara [238K]

Answer:

Step-by-step explanation:

Area of circle = 78.5 in²

πr² = 78.5

3.14*r² = 78.5

r^{2}=\frac{78.5}{3.14}\\\\=\frac{78.5*100}{3.14*100}\\\\=\frac{7850}{314}\\\\r^{2}=25\\r=\sqrt{25}=\sqrt{5*5}\\\\

r =  5 in

What is the equation for the line of reflection that maps the trapezoid onto itself? Enter your answer in the box______
nadezda [96]
Y = -1

It is an isosceles trapezoid, which is just as well, otherwise it could not reflect onto itself. The line of reflection is the same as the mirror line which is the same as the axis of symmetry.

It runs horizontally exactly through the middle of the shape.

All horizontal lines have the equation y = a value

In this case the line is <span>y=−<span>1</span></span>
