Answer:
a² + 4 a + 4
Step-by-step explanation:
( a + 2 ) ( a + 2 )
Expand brackets
a² + 2 a + 2 a + 4
Simplify
a² + 4 a + 4
Answer:
x+2
Step-by-step explanation:
x^3+6x^2+11x+6/x^2+4x+3
= x^3+6x^2+11x+6/x^2+4x+3
= (x+1)(x+2)(x+3)/(x+1)(x+3)
=x+2
Answer:
a) 1,2; 3.4
b) <1=<6, <6+<6+72=180, 2<6=108, <6=54.
<1=54
You can tell this by "these are parallel lines"
Answer: The store must sell 40 bikes.
Step-by-step explanation:
y=60x+2400
y=120x
120x=60x+2400
-60x on both sides
60x=2400
divide 60 on both sides
2400/60=40
x=40
point-slope form of a line:

where m is the slope and (x1, y1) is a point on the line.
In the case of:

the slope is 1/5 and the point is (1, 2)
With this information, we can deduce that the point (1+5, 2+1) = (6, 3) is on the line. Connecting these two points we can graph the line as follows:
