Answer:

-1

Step-by-step explanation:

It is negative 1 because the signs for the -3 are the same so you keep the -4, change the - to a +, then flip the negative 3.

Hope this helps!

Somebody please help me

Answer:

A). Scale factor = $\frac{1}{4}$

B). Length of the unknown side = 2.75 feet

Step-by-step explanation:

Part A

Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,

Scale factor = $\frac{\text{Side length of the image}}{\text{Side length of the preimage}}$

= $\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}$

= $\frac{4}{16}$

= $\frac{1}{4}$

Part B

Scale factor = $\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}$

$\frac{1}{4}=\frac{\text{Side length of the smaller rectangle}}{11}$

Therefore, side length of the unknown side = $\frac{11}{4}$ = 2.75 feet

How do I find the area of a circle?

pogonyaev

How to find the area of a circle:

The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius
If a circle has a radius of 4, its area is 3.14*4*4=50.24
If you know the diameter, the radius is 1/2 as large.
