Answer:
She will have 12 sections per fabric and 36 sections in all
Step-by-step explanation:
Betty buy 3 fabrics of 30 ft²
If she cut each to 2/5 of 1 ft²
The she will have
30 × 2/5
= 6 × 2
= 12
She will have 12 for each fabric and for the 3 fabrics, she will have
12 × 3 = 36
Charlie has 1072 more stamps than ryan. This is because if x represents the amount of stamps that ryan has, then 5x represents how many charlie has. set up an equation, and you get 5x+x=1608, because all together they have 1608. Then collect(combine) like terms and you get 6x=1608. Divide both sides by 6 and you get x=268. Therefore ryan has 268 stamps, and charlie has 5x268 stamps, or 1340 stamps, and to get how many for charlie has, subtract his by ryan's, and you get 1340-268=1072
For this case we must factor the following expression:

We take common factor 5:

We have two groups within the parentheses:
Group 1: 
Group 2: 
We factor each group:
Group 1: 
Group 2: 
Rewriting we have:
