Step-by-step explanation:
Answer:
6 * 42 = 6 * (20 + 22)
= (6 * 20) + (6 * 22) = 120 + 132 = 252
Step-by-step explanation:
Here, we want to multiply 6 by 42 using distributive property
In this case, we can have the distributive property as;
a * ( b + c) = ab + bc
Thus, we can represent 42 as (20 + 22)
so 6 * 42 becomes 6 * (20 + 22)
Using the distributive property, we have
(6 * 20) + (6 * 22)
= 120 + 132 = 252
We have been given two ratios and we are supposed to compare our ratios whether they are proportional or not.
1. We will reduce our fractions to compare our ratios. Let us simplify each of our given fractions.

Let us divide numerator and denominator with greatest common factor. We can see that 21 is GCF of our ratio.

Now we will simplify our second ratio.

GCF of our fraction is 32. Upon dividing our fraction by 32 we will get,
We can see that our both ratios are similar.
2. Now we will find decimal values of our fractions.


We can see that
.
Therefore, we can say that our ratios are proportional.
Answer:
x=-1/2, 7/2
Step-by-step explanation:
move all terms to the left side and set them equal to zero. then set eac factor to zero
