Answer:
2(xy + 2)(x + 1) (C)
Step-by-step explanation:
2x^2y + 2xy + 4x + 4
= 2xy(x + 1) + 4(x + 1)
= (2xy + 4)(x + 1)
= 2(xy + 2)(x + 1)

Answer:
A
Step-by-step explanation:
To graph an inequality, find the value on the number line. Find -3. Since this is a less than or equal to, plot a closed circle. Then shade and point an arrow in the direction which other numbers satisfy the inequality. For example, -4 is less than or equal to -3 so on. Point the arrow to the left. This is answer choice A.
Answer:
s = 10w
Step-by-step explanation:
First we need to find the slope
Since the point goes through (0,0), the slope is y/x
Using the point (1,10)
10/1 = 10
The equation is
y = mx+b
The slope is m and the y intercept is b
The slope is 10 and the b intercept is 0
y = 10x
Changing to the variables on the graph
s = 10w
