Answer:

Area of rectangle = \mathbf{x^2-4x}

Perimeter of rectangle = \mathbf{4x-8}

Step-by-step explanation:

We are given:

Length of rectangle = x

Width of rectangle = x-4

We are not given if we want to find area of rectangle or perimeter of rectangle.

So, I will be finding both

Area of rectangle

The formula used is: Area\: of\: rectangle=Length \times Width

Putting values and finding area

Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x

So, we get area of rectangle = \mathbf{x^2-4x}

Perimeter of rectangle

The formula used is: Perimeter \: of\: rectangle=2(Length+ Width)

Putting values and finding perimeter

Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8

So, we get perimeter of rectangle = \mathbf{4x-8}

I hope, it can help in solving the question.

What is the coefficient of q in the sum of (2/3q-3/4) and(-1/6q-r)?
Harlamova29_29 [7]

Answer:

The coefficient is \frac{1}{2}

Step-by-step explanation:

The given sum is

(\frac{2}{3}q -\frac{3}{4})+(-\frac{1}{6}q-r)

We can choose to add only the coeffients of q or simplify the whole sum.

=\frac{2}{3}q -\frac{1}{6}q-\frac{3}{4})-r)

We collect the LCM for the q terms;

=\frac{4-1}{6}q-\frac{3}{4})-r)

This will give us;

=\frac{3}{6}q-\frac{3}{4})-r)

Which is the same as

=\frac{1}{2}q-r-\frac{3}{4}

The coefficient is \frac{1}{2}

Stephen made the following claim:
Kay [80]

The figure below that can be used to prove that Stephen is wrong is Isosceles Trapezoid. Option C is correct. This is further explained below.

<h3>What is Isosceles Trapezoid?</h3>

Generally, Isosceles Trapezoid is simply defined as a trapezoid with base angles that are the same and non-parallel sides that are the same is called an isosceles trapezoid. If a quadrilateral has just one parallel side, we call it a trapezoid.

In conclusion, If you want to show Stephen he's incorrect, you may use the Isosceles Trapezoid in the diagram below as evidence.

if you have already covered slopes, you could also get it that way, in fact is  simpler that way.
