(-2, 2) multiplied by 2.5 is given by 2.5(-2, 2) = (-5, 5)
while (2, 1) multiplied by 2.5 is given by 2.5(2, 1) = (5, 2.5)
Answer:
No
Step-by-step explanation:
it's not always possible to factor a quadratic expression of this factoring by grouping. The method doesn't work when an expression cannot be factored as (Ax+B)(Cx+D) where A, B, C and D are integrers.
In that case, you should use other methods.

Density = mass/volume
the mass is 10578.9 pounds
the volume of a sphere is v = 4/3 πr^3
v = (4/3) (π) (4.3)^3
v = 333.04
10578.9 / 333.04 = 31.76
the final density is 31.76!!
You use point-slope form, which is y-y1=m(x-x1) , so it becomes
y-4=(-2/3)(x-3).
You can make it 3y-12=-2x+6.
Add 12 to both sides to make it 3y=-2x+18.
Lastly, divide everything by 3, so it becomes y=-2/3x+6.
