Factor out the greatest common factor from each group.
Group the first two terms and the last two terms.
(
−4x)+2xy−8y
Factor out the greatest common factor (GCF) from each group.
x(x−4)+2y(x−4)
Factor the polynomial by factoring out the greatest common factor, x−4.
(x−4)(x+2y)
I believe this is correct. Good luck.
Answer:
64 : 729
Step-by-step explanation:
Ratio of surface area
= (ratio of linear dimensions) ^2
= 1.6^2 : 5.4^2
= 256 : 2916
= 64 : 729
Equation in point slope form is written as:
y = mx + c, where m is the slope of the line and c is the y-intercept
To determine the equation when slope is given and (x,y) coordinates are given, use the below formula:
(y - y₁) = m × (x - x₁) .................. (i)
We have been given that m = 3, x₁ = 2 and y₁ = 1)
Substituting the values of m, x₁ and y₁ in (i)
(y - 1) = 3 × (x-2)
⇒ y - 1 = 3x - 6
⇒ y = 3x - 5
So the required equation is y = 3x -5, here 3 is the slope and -5 is the y-intercept
