I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)
Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.
Answer:
(15n^2-5n+45)/5
=3n^2-n+9
Answer:
Draw the triangle.
Draw the perpendicular bisector to each side of the triangle. Draw the lines long enough so that you see a point of intersection of all three lines.
Draw the circle with radius at the intersection point of the bisectors that passes through one of the vertices
A) 1/5 + 5/9
find common denominator:
9*5 = 45
pillow case: 1/5 = 9/45
table cloth: 5/9 = 25/45
9/45 + 25/45 = 34/45 was used
B. using 45 as the denominator the full piece of cloth would be 45/45
fraction left over = 45/45 - 34/45 = 11/45 left
C. from A the pillow case uses 9/45, they have 11/45 left, because 9 is less than 11, they have enough to make a pillow case
Answer:
20
Step-by-step explanation:
P-R(n)=C
you subtract R in order to get it to the other side and multiply n to do the same. that way you get C by itself and have your answer
