Find the area of the following figure. Explain how you found your answer.

iragen [17]

Answer:

Below

Step-by-step explanation:

Let's say that each square on the grid represents 1 cm

First find the area of the two triangles

For the larger one: A = bh/2

A = 3 x 3 / 2

= 4.5 cm^2

For the smaller one : A = bh/2

A = 2 x 2 / 2

= 2 cm^2

For the rectangle : A = lw

A = 4 x 5

= 20 cm^2

Add them all up to get the area

4.5 + 2 + 20 = 26.5 cm^2

Hope this helps!

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify points from graph.

Point (8, 5)

Point (4, 2)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(8 - 4)^2 + (5 - 2)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{4^2 + 3^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 9}$
[√Radical] Add: $\displaystyle d = \sqrt{25}$
[√Radical] Evaluate: $\displaystyle d = 5$

Raphael graphed the system of equations shown. y = – 3 y = x – 0.8 What is the best approximation for the solution to this syste

ira [324]

The answer is C (-2.2, -3).

In order to find the ordered pair we must use what we know from the first equation in the second. We already know that y = -3, so that goes into the second equation.

y = x - 0.8
-3 = x - 0.8
-2.2 = x
