[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg <em>a</em> = 7.5
Leg <em>b</em> = 10
Hypotenuse <em>c</em> = <em>c</em>
<em />
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute in variables [Pythagorean Theorem]: 7.5² + 10² = c²
- Rewrite: c² = 7.5² + 10²
- Evaluate exponents: c² = 56.25 + 100
- Add: c² = 156.25
- [Equality Property] Square root both sides: c = 12.5

Hello from MrBillDoesMath!
Answer:
a = 2.7
Discussion:
(2/3) ( 6a + 9 ) = 16.8 => the Distributive law
(2/3) (6a) + (2/3)9 = 16.8 =>
4a + 6 = 16.8 => subtract 6 from both sides
4a = 16.8 -6 = 10.8 (divide both sides by 4)
a = 10.8/4
= 2.7
Thank you,

Answer:
(x) = 
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject, that is
y = 7x - 6 ( add 6 to both sides )
y + 6 = 7x ( divide both sides by 7 )
x = 
Change y back into terms of x, hence
(x) =
