-2 because in the second equation it is : 2x. If you multiply x in the first equation by -2 it will cancel out 2x in the second equation. -2x cancels out 2x. -2x+2x=0
Answer:
(a) 1/6
(b) 1/2
(c) 1/3
Step-by-step explanation:
There are 6 possible outcomes.
(a) The number is 2: only 1 outcome out of 6, hence 1/6
(b) The number is even: {2, 4, 6} - 3 outcomes out of 6, hence 3/6 = 1/2
(c) The number is greater than four: {5, 6} - 2 outcomes out of 6, hence 2/6 = 1/3
Answer: 
Step-by-step explanation:
Given
The rug is 4 feet longer than its width
Suppose the length of the width is x
Length is given by x+4
So, the product of length and width is equal to the area of the rug
![\Rightarrow x\left(x+4\right)=A\quad\quad [\text{A=Area of rug}]](https://tex.z-dn.net/?f=%5CRightarrow%20x%5Cleft%28x%2B4%5Cright%29%3DA%5Cquad%5Cquad%20%5B%5Ctext%7BA%3DArea%20of%20rug%7D%5D)
