The way that you would do this is by taking

out of the binomial, or as I like to think about it, 'un-distributing'. :p

out of

, you end up with

.
When you take

out of

, you get

.
Put it together, and the solution is

-

Hope I helped!!
2 kg is bigger because 1 kg=1000 g and so 1500 g would equal 1.5 kg which is smaller than 2 kg
Answer:
See below.
Step-by-step explanation:
a. 973 * 80
= 973 * 8 * 10
= 7784 * 10
= 77,840.
b. 56 * 2000
= 2*56 * 1000
= 112,000.
c. 5.7 * 300
= 5.7 * 3 * 100
= 17.1 * 100
= 1710.
d. 0.46 * 50
= (0.46 * 100) / 2
= 46 / 2
= 23.
First you need to find the slope, which is (y2-y1)/(x2-x1)
Plug the points in as (1-4)/(-1-1) -> -3/-2
The slope is 3/2, or 1.5
Point slope form is y-y1 = m(x-x1)
Plug in the slope (m) and the first point
y-4 = 1.5(x-1) <-- That's point slope form
To get standard form (ax+by=c), you can use point slope form
y - 4 = 1.5(x - 1)
y - 4 = 1.5x - 1.5
y = 1.5x + 2.5
-1.5x + y = 2.5 <-- Standard Form
