I got it right
Answer:
I cant see the whole thing
<span>|3x|>0
3x> 0 then x > 0
-3x > 0 then x < 0
answer
x > 0 or x < 0</span>
Use elimination to find both values.
Subtract the second equation from the first equation
x + 15y = 40
- x + 10y = 30
————————
5y = 10
y = 2
Plug in the value for y into one of the equations. I’m going to put it in the second equation.
x + 10(2) = 30
x + 20 = 30
x = 10
x = 10
y = 2
The length and width of the rectangle are (10x + 7) and (x – 2). Then the correct option is C.
<h3>What is polynomial?</h3>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Mandisa draws a rectangle to represent the area of her yard. The area can be represented by 10x² – 13x – 14.
We know the formula of area
Area = length × width
On factorizing, we have
Area = 10x² – 13x – 14
Area = 10x² – 20x + 7x – 14
Area = 10x(x – 2) + 7(x – 2)
Area = (10x + 7)(x – 2)
Thus, the length and width of the rectangle are (10x + 7) and (x – 2). Then the correct option is C.
