Step-by-step explanation:
Assuming the fractions are being multiplied
Factorise the denominators of both fractions
x² - 3x - 10 = (x - 5)(x + 2)
x² + x - 12 = (x + 4)(x - 3)
The product can now be expressed as
× 
Cancel (x - 5) and (x + 2) on the numerators/ denominators, leaving
= 
You subtract the 11 from both sides, then you get -3x = 33. Next, you divide -3 from both sides, and you get x= -11
Answer:
It is the easiest way to graph an equation.
Step-by-step explanation:
Isolating the y variable is also slope-intercept form.
Slope intercept form is the easiest form to use when graphing.
y = mx + b
m is the slope, b is the y-intercept.
it makes it way easier to graph an equation when it is in slope intercept form.
I hope that helps! =)
The perimeter of these can be found by adding length and width and then multiplying by two.
Rectangle A: (with all of the variables already doubled)
2x + 16 + 2x - 2
2x + 2x + 16 - 2
4x + 14
So rectangle A's perimeter is 4x + 14.
Rectangle B: (Still with all the variables already doubled)
8x + 10 + 6x - 4
8x + 6x + 10 - 4
14x + 6
So rectangle B's perimeter is 14x + 6
And now to subtract the two.
(7x + 3) - (4x + 14)
14x + 6 - 4x - 14
14x - 4x + 6 - 14
10x - 8
So it would be C.
