Answer:
18m+20
Step-by-step explanation:
9m(2)+10(2)=18m+20
<span>4ab + 4a − 3b − 3
=4a(b + 1) - 3(b+1)
= (b+1)(4a - 3)
(b+1) and (4a - 3) are factors

Answer:
x = 144
Step-by-step explanation:
Angle sum of heptagon = 900
5x + 90 + 90 = 900
5x + 180 = 900
5x + 180 - 180= 900 - 180
5x = 720
Divide both sides by 5
x = 144
The vector would have to be a scalar of (4,-1) in order to be parallel to it
so
4 = 8t -1 = 2t
t= 4/8 = 1/2
-1=2t
t= -1/2
(Interchange the x and y-values)
(Solve for y)
