Answer:
<h2><u><em>
a²+2ab+b²-c²</em></u></h2>
Step-by-step explanation:
Solve:
(a+b+c) (a+b-c)=
(a²+ab-ac+ab+b²-bc+ac+bc-c²)=
a²+ab-ac+ab+b²-bc+ac+bc-c²=
a²+2ab+0ac+b²+0bc-c²=
a²+2ab+b²-c²
Answer:
Let's find out!
Step-by-step explanation:
So we have to set up an equation
Let x= # of ribbons that can be cut
Thus:
So, we cannot have 36/7 ribbons! It's not possible!
So we just simplify!
There we go! She can cut 5 ribbons off!
I'll let you figure out the last one!
Hope this helps!
P.S. Stay Safe!
To find miles per hour you divide the number of miles by the number of hours
(7 1/2)/(3/8) = (15/2)(8/3) = 20 mph
