Answer:

x = 20.

Step-by-step explanation:

This is a right triangle, so by Pythagoras:

29^2 = x^2 + 21^2

x^2 = 29^2 - 21^2

x^2 = 400

x = √400

x = 20.

Which expression can be expanded using the binomial theorem?

kirill [66]

Answer:

The third choice: (x² - 1)³

Step-by-step explanation:

That is the only expression that is a binomial. Binomial means "two numbers". For this expression, x² is one number, and -1 is the other. Choice 1 is a monomial (one number) and choices 2 and 4 are trinomials (three numbers)

Solve the equations with variable on both sides: 8x=10x + 20 A. X= -10 B. X= -35 C. X= -23 D. X= -40

liberstina [14]

The correct answer is A

A) $8(-10)=10(-10)+20$ becomes $-80 = -80$

B) $8(-35)=10(-35)+20$ becomes $-280 \neq -330$

C) $8(-23)=10(-23)+20$ becomes $-184 \neq -210$

D) $8(-40)=10(-40)+20$ becomes $-320\neq -380$
