Answer:
x-9
Step-by-step explanation:
-3(x+3)+4x
-3x-9+4x
-3x+4x-9
x-9
Answer:
x (7+2x) = 372,
where 372 is the are of this rectangle, and is its width.
Step-by-step explanation:
The width of this rectangle is . Twice that width will be equal to .
The length of this rectangle is seven more than twice the width of this rectangle, or seven more than . The length of this rectangle will thus equal to .
The area of a rectangle is equal to the product of its width and its length. The width of this rectangle times its length will be equal to .
For this rectangle, this area is equal to 372. In other words,
.
This equation about represents the relationship between the width, length, and the area of this rectangle.
Isn't this perpendicular for a cross shape
2+2-1 that's three quick maths.
Answer:
Step-by-step explanation:
I believe that there was a typo in this question
Unfortunately, there are no roots of this equation without one of two things:
1. Another equation, and you could solve for the roots in a system of equations
2. The value of y is actually supposed to be 0
In the second case, you would solve it like this:
-3x = 0
factor out x
x(x-3) = 0
x = 0, x = 3
