Answer:
4x-13
Step-by-step explanation:
Let the number is x.
We know that triple of a number is 3 times that number i.e. 3x
The difference between triple the number and thirteen 3x-13
Now, we need to add a number to the difference between triple the number and thirteen. So, the expression can be written as :
x+3x-13 = 4x-13
Hence, the expression is (4x-13).
The correct answer is 2 Solutions , see it’s how many times the two lines intersect, so 2
Answer:
a=1; b=14
Step-by-step explanation:
you have to form a perfect square
(a+b)²=a²+b²+2ab
If you add a one you will get a perfect square
x²+2x+1 = (x+1)²
if you added a one in one side you have to added to the other side too
(x+1)² = 13+1
(x+1)² = 14
