A² + b² = c²
30² + 72² = c²
<u />900 + 5,184 = c²
6084 = c²
(Square root both sides)
c = 78 m

Answer:
we know that q=-18
So if we see the fraction below it says q/3
We know that q is -18
Therefore, you substitute it in for q and you get
-18/3 which equals -6
X^2 - 7x = -12
2x - 7x = -12
-5x = - 12
x = 12/5
or
x = 2.4
1.07x is the sum of the equation
Jan has 500 pages of paper.
She has a report of 16 pages.
But a report is printed on both sides of the page.
So the complete report shall be printed on 8 pages.
Now as the total pages are 500
We shall divide 500 by 8 and convert the simplified fraction to mixed no.
Now

So we shall be able to print 62 complete copies of the report which shall use 62 × 8 = 496 pages.
Number of pages left = 500 - 496 = 4 pages.
