Let's go ahead and find the difference in height in meters.

1.7-1.5= 0.2 meters

There are 100 centimeters in a meter.

0.2*100= 20

The correct answer is "C". 20 cm.

I hope this helps!

Choose the correct simplification of the expression (−2x + 4y)(3x − 7y).

Rudik [331]

-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy

—> -6x2(expo) - 28y2(expo) + 26xy

Check the answer again just to be sure, it’s been a while since I’ve had algebra!

Answer:

$y=\frac{3}{2}x+4$

Step-by-step explanation:

So the line C equation is $y=\frac{3}{2}x+2$ and line D is parallel to it and it passes through the point (4,10) and we need to ding the equation for line D.

So first we have a graph with line C listed and (4,10).

And we can keep listing more equations till we find the right one which is $y=\frac{3}{2}x+4$ .

So I got this by knowing that in parrelel lines the slope is the same but the y intercept changes which is why it was fast to find the answer.
