Hey there! :)
In order to the find the missing side length of this triangle, we'll need to use the Pythagorean Theorem!
That equation is : a² + b² = c²
a = adjacent side
b = long side of rectangle
c = hypotenuse
We're already given the values of both a & c, so let's plug everything in!
a² + b² = c² → a = 10 , b = ? , c = 20
(10²) + b² = (20²)
Simplify.
100 + b² = 400
Subtract 100 from both sides.
b² = 400 - 100
Simplify.
b² = 300
Get the square root of b² & 300.

Simplify!
b = 17.3
So, the missing side length is the first answer choice : 17.3~Hope I helped!~

Question: What is the coefficient in the expression 10x²-7?
The coefficient in the expression
is 10
<h3>What is Coefficient?</h3>
A numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
According to the question,
The expression given is 
The variable given is x
We need to find the coefficient in the expression.
In the given expression x is the variable and the number before the x is coefficient which is 10 .
Hence the coefficient in the expression is 10.

All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.
Answer: The quotient is (x-2).
Step-by-step explanation:
Since we have given that

Now, we have to find the quotient of the above expression.
So, here we go:

Now, we will divide the above simplest form with g(x):

Hence, the quotient is (x-2).
