Option A
is one way to determine the factors of
by grouping
<em><u>Solution:</u></em>
Factoring by grouping means that you will group terms with common factors before factoring
<em><u>Given expression is:</u></em>

Group the first two terms together and then the last two terms together.

We can see that
is common in first two terms
And 3 is common in last two terms
Factor them out


Thus option A is correct
Answer: a) 278382 oz
b) 43 oz
c) 64.1 oz
Step-by-step explanation:
a) 8 T. 1,398 lb. 14 oz. × 6
First we need to change it in 'oz'.
As we know that

so, it becomes,

8 T. 1,398 lb. 14 oz. × 6 becomes

b) 349 lb. 6 oz. ÷ 130
It becomes,

c) 6 T. 294 lb. ÷ 3,071
First it becomes,

At last it becomes,

Hence, a) 278382 oz
b) 43 oz
c) 64.1 oz
I believe the answer would be the second option. The equations given above when graph would intersect only once with each other. They intersect at only point (0,6/5). These are the values of x and y that will agree to the equation. Two equations in a set will always intersect at only one point.
