Answers
Answer:
99
Step-by-step explanation:
You can solve it by Squaring/multiply 18 by itself and 15 by itself then subtract them both:
(18 × 18) - (15 × 15)
324 - 225
99
You could also do difference of two squares:
(x² - y²)
= (x + y) (x - y)
= (18 + 15) (18 - 15)
= (33) (3)
= 99
Answer:
99Step-by-step explanation:

Is it possible to form a triangle using 15 in, 12 in, 8 in ? Why or why not?
Answers
Answer:
No
Step-by-step explanation:
Use the pythagoreon theory
15^2+12^2=8^2
454=64
Since they do not equal the same number you can not form a triangle, and no matter how many times you switch the numbers around they will not equal.

Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.
Angle one: 2x°, angle two: xº, angle 3: (X + 8)°
Answers
Sum of all angles in a triangle = 180°
Which means :-
∠1 + ∠2 + ∠3 = 180°
[tex]2x + x + x + 8 = 180°[/tex]
[tex]4x + 8 = 180°[/tex]
[tex]4x = 180 - 8[/tex]
[tex]4x = 172[/tex]
[tex]x = \frac{172}{4} [/tex]
[tex]x = 43[/tex]
Angle 1 :-
= 2x
= 2 × 43
= 86°Angle 2 :-
= x
= 43°Angle 3 :-
= x + 8
= 43 + 8
= 51°[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]

Answer:
The answer is 12Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(1,3) and (0,−9)
The slope is
[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]

Question Says:-An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?
Answer:-See, let us consider the sides as l as per question.
And, perimeter as p as per question.
We know that:-
The sum of all the boundary gives us the perimeter of the figure.
It is Equilateral Triangle, so the equation will be:-
[tex]l + l + l = p[/tex]
Now, adding it up, we get
[tex]3l = p[/tex]
So, 3l=p relates the side and perimeter.

The roots of a quadratic equation are 7 and -3. Which quadratic equation has these roots?
(x + 7) (x – 3) = 0
(x - 7) (x + 3) = 0
(x – 7) (x – 3) = 0
(x + 7) (x + 3) = 0
Answers
Explanation: Put both equations equal to 0, so it looks like this: (x - 7) = 0 (x + 3) = 0
It doesn’t matter what you do first but I’ll start with (x - 7) = 0
First you remove the parenthesis
x - 7 = 0
Next you add the 7 on both sides. You do this to cancel the 7 so that the x is by itself.
x = 7
It’s the same thing for the (x + 3) = 0 but I’ll show you anyways
Remove parentheses
x + 3 = 0
Subtract the 3 from both sides that way the 3 cancels out and the x is on its own
x = -3

x = 25
Step-by-step explanation:
3x + 5 + 5x - 25 = 180 (collect like terms)
8x - 20 = 180 (add 20 on both sides)
8x = 200 (divide by 8 on both sides)
x = 25
Since they are supplementary that mean together they add up to 180 so that's why I added them together.
