Answer:
The Pythagorean Theorem gives us a2 + b2 = c2 for a right triangle, where c is the hypotenuse and a and b are the smaller sides.
9 + 3 × 2² - 1 × 4
= 9 + 3 × 4 - 1 × 4
= 9 + 12 - 1 × 4
= 21 - 1 × 4
= 21 - 4
= 17
Follow the order of PEMDAS, where,
P = Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction

Step-by-step explanation:
try multiplying the numbers
So some quick tips for inequalities:
**What you do to one side you HAVE TO do it to the other 2**
**If you ever divide a negative number past the inequality signs, the signs FLIP!!**
(e.g. 2>-5x>25)
-2/5 <x < -5
I hope that this has helped!
