First, we can see that there are four sides, and none of these equation contradict each other, so it is safe to say that <em>this is a quadrilateral</em>.
Second, all of the equations have the slope of <em>0 or undefined</em>, so it is a rectangle.
Lastly, the four points of intersection shows us that the side lengths are <em>3 and 5</em> units, so the area of it is 15 units².

What is linear equation?
An equation in which the highest power of the variable is one is known as linear equation.
We will find number of pizza slices as shown below:
Let pizza originally have x slices.
Adam eats 20% of a pizza
= 0.2x
Bethany eats 1/3 of pizza
=1/3(x)
Charlie eats the remaining 14 slices
0.2x+1/3(x)+14=x
14 = x - 0.2x - 1/3(x)
14 = x - x/5 - x/3
14 = (15x - 3x - 5x)/15
14*15 = 7x
By dividing both sides by 7, we get
30 = x
x = 30
Hence, the pizza originally have 30 slices.

Answer:
y = √(55).
Step-by-step explanation:
Triangles ADC and DBC are similar, so we have
(6+5) / y = y / 5
11/y = y/5
y^2 = 55
y = √(55).
Answer:
Multiply 2*15
Step-by-step explanation:
2 · 15 - 2 ÷ 5
PEMDAS
Parentheses none
Exponents - none
Multiply and divide from left to right
2*15 = 30
Then 2÷5 = .4
30 - .4 = 29.6
