Help with this problem please. 3x(x-1)

3x² - 3x

Step-by-step explanation:

Assuming you require to simplify the expression

Given

3x(x - 1) ← multiply each term in the parenthesis by 3x

= (3x × x) + (3x × - 1)

= 3x² + (- 3x)

= 3x² - 3x

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
