Since you are given the area, we can solve for radius with this equation:
The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is
22 units²
X^2+3x=24, halve the linear coefficient, square it, and add it to both sides
In this case (3/2)^2=2.25
x^2+3x+2.25=26.25 now the left side is a perfect square...
(x+1.5)^2=26.25 take the square root of both sides
x+1.5=±√26.25 subtract 1.5 from both sides
x=-1.5±√26.25
x=-1.5-√26.25 and -1.5+√26.25
x≈ -6.62 and 3.62
Answer:
There are in cents: 3 or 4 if you count it. And in dollars: 4 different ways to make 30 dollars or 30 cents.
Step-by-step explanation:
Cents: 30 pennies

if you can use both : 1 nickel and a quarter
I can not tell if that is 30 dollars or 30 cents so I will do both :
Dollars: 300 pennies
60 nickels
30 dimes
120 quarters
