Answer:

$\boxed {p = -7}$

Step-by-step explanation:

Solve for the value of $p$ :

$-3 + 4p = -31$

-Add both sides by $3$ :

$-3 + 3 + 4p = -31 + 3$

$4p = -28$

-Divide both sides by $4$ :

$\frac{4p}{4} = \frac{-28}{4}$

$\boxed {p = -7}$

Therefore, the value of $p$ is $-7$ .

What is the area of the figure?

statuscvo [17]

Answer:

Step-by-step explanation:

We can divide this into 3 shapes, a square, rectangle, and triangle.

Let's solve the area of each of these shapes and add them all up.

First, let's solve the square.

We know that one side is 4 ft so that means that the other side is also 4ft.

4*4=16

Our area of the square is 16ft^2

Let's solve the rectangle next,

Its length is 12ft and its width is 4ft.

12*4=48

So the rectangle area is 48ft^2

Now for the triangle

Remember that area of a triangle is a=hb/2

Our height is 12 ft and our base is 4ft

12*4=48

48/2=24

Triangle is 24ft^2

That means that we can add them all up

24+48+16=88

88ft^2 or 88

The length of my rectangular garden is 1 foot more than twice its width. The area of my garden is 55 square feet. What are the d

loris [4]

Answer:

Width = 5

Length = 11

Step-by-step explanation:

Let :

Width, = x

Length = 2x + 1

Area of rectangular garden is given as 55 ft²

Area of a rectangular garden, A = Length * width

Hence,

x * (2x + 1) = 55

2x² + x = 55

2x² + x - 55 = 0

Using the quadratic equation formula :

a = 2 ; b = 1, c = - 55

-b ± sqrt(b² - 4ac) / 2a

Using the quadratic equation solver to save computation time :

The roots are :

-5.5 and 5

Dimension can't be negative ; so x = 5

Hence,

width, x = 5

Length, 2x + 1 = 2(5) + 1 = 10 + 1 = 11

Hence,

Width = 5

Length = 11

Question 3: Quadrilateral A'B'C'E' is the image of quadrilateral ABCE after a dilation centered

jonny [76]

<h3>Answer: Scale factor = 1/2 = 0.5</h3>

==========================================================

Explanation:

We have AB = 3 and A'B' = 1.5; the ratio between the two segment lengths is (A'B')/(AB) = (1.5)/(3) = 1/2 = 0.5

Similarly,

(B'C')/(BC) = (3)/(6) = 1/2 = 0.5
(C'E')/(CE) = (2.5)/(5) = 1/2 = 0.5

You only need to pick one of these statements to be able to find the scale factor. The scale factor of 1/2 or 0.5 indicates that the image is half as small compared to the preimage. More specifically, each segment of the image is half as small compared to the corresponding segment on the preimage.

A'B' is half as small as AB
B'C' is half as small as BC
C'E' is half as small as CE
A'E' is half as small as AE

We don't have numbers for AE and A'E', but the last statement above must be true because the dilation applies to all segment lengths.
