x = 10
Step-by-step explanation:
We know x = 6
asked: x + 4
Plus it in =>

Answer:
The perimeter of rectangle A is 8x+6y or 2(4x+3y)
Step-by-step explanation:
The perimeter of a figure is the sum of its boundary dimensions.
The perimeter of rectangle A is:
Factorizing,
Answer:
y=2(x+2)(x+3)
Step-by-step explanation:
First, we need to factor the right side:
y=2(x^2+5x+6)
Now, we can have an incomplete equation like this:
y=2(x+_)(x+_)
In the blanks, we need to fill out numbers that add to be 5 and multiply to be 6. What are factors of 6? 6 and 1, 2 and 3. Do 6 and 1 add to be 5? No. Do 2 and 3 add to be 5? Yes!
So, our factored form is
y=2(x+2)(x+3)
Answer:
The answer is c= 8
Step-by-step explanation:
If the function f(x) is negative over the entire interval, then the interval must be from 0 (exclusive) to negative infinity. In another notation, it can be represented as (-∞, 0). To represent this in the coordinate system, all the values below the x axis can be shaded to indicate that these are the possible values of the function.
