You first subtract 5x from both sides and end up with -3y=21-5x. In order to isolate the variable you need to divide -3 from both sides. Your equation would then be y= -7+ 5/3x. I hope this helps love! :)
Answer: the root of 145 so b
Step-by-step explanation:
Answer:
the answer would be 6x^2(x+6)(x-2)
Step-by-step explanation:
6x^4 + 24x^3-72x^2
= 6x^2(x^2+4x-12)
= 6x^2(x+6)(x-2)
Answer:
Step-by-step explanation:
Given
← factorise numerator and denominator
2x² - 18 ( factor out 2 from each term )
= 2(x² - 9) ← difference of 2 squares
= 2(x - 3)(x + 3)
and
x² + 4x - 21 = (x + 7)(x - 3) , then
= 
← cancel common factor (x - 3) on numerator/ denominator
=
