Simplify. Express using exponents. 5^9x5^3

Answer:

Yes

Step-by-step explanation:

A right triangle's formula, according to Pythagorean's Theorem, is a² + b² = c². a and b are the two legs, and c is the hypotenuse. To solve, we must substitute the variables with the given measurements.

9² + 12² = 15²

Let's now solve:

81 + 144 = 225

225 = 225

The formula works out in the end, so it is a right triangle!

The statement Which can be represented by the expression 17 – 2x is the difference between 17 and twice a number x, the correct option is C.

What is an expression?

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that;

The expression= 17-2x

Now,

The expression 17 - 2x represents;

the difference between 17

and 2x is twice a number x.

Therefore, the answer of the given expression will be the difference between 17 and twice a number x.
