Answer:
(x+4)(x+2)
Step-by-step explanation:
Distributive property of 2 binomials:
First, outer, inner, last
(a+b)(c+d) = ac+ad+bc +bd
Factor x^2 into x*x
Factor 8 into 2*2*2
Find what two numbers add up to 6 and multiply to get 8
1 and 8 do not work because they add up to 9. 2 and 4 work because they add up to 6.
Check: (x+4)(x+2)
First: x*x = x^2
Outer: 2*x
Inner: 4*x
Last: 2*4 = 8
Add together: x^2+2x+4x+8 = x^2+6x+8
Answer:
p to q is 3,7 and the distance between p and r is 7,3

Answer:
(0,-1)
Step-by-step explanation:
Let the ends of the line segments be A(-4,3) and B(5,-6).
Ratio=4:5
By the concept of cordinate geometry,
x=(mx2+nx1)/(m+n)
y=(my2+ny1)/(m+n)
where m and n is the ratio m:n.
So, here the cordinates are
x={4(5)+5(-4)}/(4+5)
x=(20–20)/9
x=0
y={4(-6)+5(3)}/9
y={-24+15}/9
y=(-9)/9
y=(-1)
Therefore the cordinates of the point that divides the given line segment in the ratio 4 : 5 is (0,-1)
