Answer:

See below.

Step-by-step explanation:

First, it's obviously a line so the equation is a linear equation.

In order to find a linear equation, we first need the slope and the y-intercept. Recall the slope-intercept form: $y=mx+b$ , where m is the slope and b is the y-intercept.

We already know the point (0,3) which is the y-intercept. Thus, b=3.

To find the slope, use the slope formula:

$m=\frac{\Delta y}{\Delta x} =\frac{2-3}{3-0}=-1/3$

Thus, the equation is:

$y=-\frac{1}{3}x+3$

FIND THE FOLLOWING USING THE GIVEN TRIANGLE...PLEASE HELP ME SUCK AT MATH...SOS!!! ASAP!!!!

SIZIF [17.4K]

perimeter = 20 +20 +24 = 64 feet

area = 12^2 + x^2 = 20^2

144 + x^2 = 400

x^2 = 256

x = sqrt(256) = 16 feet

area = 1/2 x 16 x 24 = 192 square feet

cost = 192 x $2 = $384

What is the area of the rectangle

Whitepunk [10]

Answer:

See explanation.

Step-by-step explanation:

Area=A

length=l

width=w

$A=lw$

$A=\frac{7}{3}*\frac{9}{4}$

$A=\frac{56}{12}$

$A=\frac{14}{3}$

$A= 4\frac{2}{3}$

Answer:

Part A)

The polynomial is:

$A=4(x+8)(x+10)$

Or, expanded:

$A=4x^2+72x+320$

Part B)

When the width of the frame is two inches, the area of the picture including the frame is 480 square inches.

Step-by-step explanation:

Part A)

For solely the picture, the width is 16 inches, and the length is 20 inches.

If we include the width of the frame, then we will have to add x to both sides of the 16 inches. Then the new width will be (16 + 2x) inches.

Likewise, the new length will be (20 + 2x) inches.

The area of a rectangle is given by its width multiplied by its length. Then the polynomial that represents the area will be:

$A=(16+2x)(20+2x)$

To simplify calculations, we can factor out a two from both factors. Thus:

$A=2(8+x)\cdot 2(10+x)=4(x+8)(x+10)$

Expanded, this will be:

$A=4(x^2+18x+80)=4x^2+72x+320$

Part B)

When the width of the frame is two, x = 2. Then the area is:

$A=4(2+8)(2+10)=4(10)(12)=40(12)=480\text{ inches}^2$

The area of the picture including the frame will be 480 square inches.
