What is the definition of a reciprocal? Will give brainilest.

Reciprocal: what to multiply a value by to get 1. The reciprocal is also called the "Multiplicative Inverse".

That's the official definition. Basically... the reciprocal is whatever value you are working with... but the numerator and denominator are switched. Remember that if you are working with a whole number/ value... it is still a fraction divided by 1. For example, the number 6 is the same as 6/1. Another example would be x is the same as x/1. Knowing this, the reciprocal of x (which is x/1) is 1/x

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

it is a reproduction.
