1*5=12.75
2*4=9.6
so nine pens cost 3.15
one pen will be 0.35$
so one pencil will be .20$
Answer:
Assuming "x2" is x squared:
5x(x2-4x+2)
(5x(x2)+5x(-4x)+5x(2))
<u>5x^3-20x+10x</u>
For these polynomial multiplication problems, just distribute the number outside the parentheses.
basically you would do length x width
5x and x
6 and 4
For AC:
AC= root((a-0)^2 + (b-0)^2)
AC= root((a)^2 + (b)^2)
For BD:
AC= root((a-0)^2 + (0-b)^2)
AC= root((a)^2 + (-b)^2)
AC= root((a)^2 + (b)^2)
Therefore,
AC=BD
Answer:
Take 1651 divided into 13 you get 127 so they can buy 127 posters . Then they sold them for 20 dollars a piece so take 20 times 127 which is 2,540 dollars that’s the money they got .
