A lamp is perfect... Measure length and width and multiply them together...
Answer:
D
Step-by-step explanation:
group them first :
( x3+5x2) and ( -6x-30)
then simply by gcf ( greatest common factor) :
x2(x+5) and -6(x+5)
and just add them together:
x2(x+5)-6(x+5)
bonus :
it can be written as (x2-6)(x+5)
Answer: a. 
Step-by-step explanation:
Sub x=-5+2y
2(-5+2y)+4y=14
y=3
3x-4y=12
4y=3x-12
y=(3x-12)/4
y=(3/4)x-3
