What is the length of leg s of the triangle below?
Answers
Hey there!
There are a few ways to do this, but I'll give you the one I can explain best.
This is a right triangle. We know this because one of the angles is 90º.
The lengths of the sides of the right triangle can be represented by the following equation:
a² + b² = c²
We already have the values for a and c, c being the hypotenuse.
3² + b² = (√18)²
Let's square a and c.
9 + b² = 18
Subtract 9 from each side of the equation.
b² = 9
To find the final value for b, find the square root of each side of the equation.
b = 3
Your answer is 3, or option D.
Hope this helps!

What is an expression?
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Juanita organizes her magazines into 3 equal piles. She has a total of 18 magazines.
The number of magazines in each pile will be calculated as,
N = 18 / 3
N = 6 piles
Therefore, the number of magazines in each pile will be 6.

Let's find the GCF: it's at least 9, since both numbers are divisible by 9 (36/9=4; 45/9=5)
so 81 (the sum of the numbers) equals 9*9 (where 9 is the gfc)
and the answer is 81=(4+5)*9, where 4+5 is the "another sum".

a+(b+c)=(a+b)+c
and the commutative property that says
a+b=b+a
use together and get
(8x+14)+(9x-5)=8x+9x+14-5
add like terms
8+9=17
therefor
17x+14-5
14-5=9
17x+9 is the simpliefid form
