When adding fractions all denominators must be the same. You multiple 2/3 by 4 so it becomes 8/12 and the same with the others. The answer is 19/12
Answer: 3x + 15
Step-by-step explanation:
In order to use the distributive property, you simply multiply the number on the outside by both the number inside the parenthesis
So, in this case, we would multiply 3 by X and 3 by 5
3 times x = 3x
3 times 5 =15
Your new equation is then made by adding these two together
3x+15
Answer 3x + 15

Answer:
4V
Step-by-step explanation:
The coefficient of each V is 1
So, 1V + 1V + 1V + 1V
= 4V
Step-by-step explanation:
x⁴+3x³-4x²=0
x²(x²+3x-4)=0
x²+3x-4=0
x²+4x-x-4=0
x(x+4)-1(x+4)=0
(x+4)(x-1)=0
x=-4 or 1
x can't be negative
therefore x=1
x+4=1+4=5
