Answer:5 and 3
So we let the number take the letter b, anc the expression of the question is:
b^2+15=8×b.....so
b^2+15=8b
Then we take the 8b to the other side of the equal sign so that it becomes...
b^2+15-8b=0
Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...
From there we work out to get two different numbers...either b-5=0
b=5
Or b-3=0
b=3
So the two numbers are 5 and 3
The correct answer is B. 3.2
You can find this answer by using any of the points on the graph and putting them into the given equation. Then you can solve for the constant. For the purpose of this example, we will use (2, 6.4)
Height = Constant * Width ---> Plug in known values.
6.4 = Constant * 2 ----> Divide both sides by 2
3.2 = Constant
This will work with whatever numbers you use from the graph.
we gonna need a little more than that to help ya, bud.

Answer:</h3>
= 18°
= 4(18°) = 72°
<h3>
Step-by-step explanation:</h3>
Given:
- One angle in the triangle is 90°
- One angle that isn't 90° is 4 times larger than another angle that isn't 90°
Angles:
= 90°
= x
= 4x
Solution Pathway:
Under the rules for any triangle, a triangle's interior angles must add up to 180°. Using this, we can set up the equation:
- sum of the interior angles = 180°
Now let's solve for x.
- 90 +x + 4x = 180
- 90 + 5x = 180
- 5x = 90
- x = 18°
Now that we know x is 18°, lets plug this value into the two unknown acute angles.
= 18°
= 4(18°) = 72°
