Answer:
Let the no.be X
when multiplied by 4 = 4X
68-4X=3(X+4)
68-4X=3X+12
collecting like terms together,
7X=56
therefore; X=8
hence ,the number is 8.
hello :
y = 2(x + 3)² - 5
y = 2(x²+6x+9) -5
y = 2x² +12x +13...(answer : A) y=2x^2+12x+13 )
Option (a) is correct.

Answer:
x=3
Step-by-step explanation:
Because it is equilateral, all the sides are equal. so you can make your equation
3(2x-3)=21
Distribute the 3 throughout, giving you 6x-3=21
Subtract the 3 from both sides, and you are left with 6x=18
Divide 18 by 6 and you get 3.
