2r2+2r−24=0
Step 1: Factor left side of equation.
2(r−3)(r+4)=0
Step 2: Set factors equal to 0.
r−3=0 or r+4=0
r = 3 or r = −4
Hello! First, let's add 1 to the tax rate in decimal form. 6.5% is 0.065. 1 + 0.065 is 1.065. Multiply that number by 25 to get 26.625 or 26.63 when rounded to the nearest penny. The total cost of the movie is $26.63.
Note: If a question asks for the total cost with tax, always add 1 to the tax rate in decimal form. That way, you will get straight to the answer and not have to do any complicating work.
17 is a prime number whereas 26,44 and 65 are the composite numbers.
<u>Step-by-step explanation:</u>
The number 17 does not belong with 26, 44 and 65.
Here 26 is divisible by 2 and 13.
44 is divisible by 2, 4 and 11.
65 is divisible by 5 and 13
But 17 is divisible by 1 and itself, that is it's a prime number, whereas the other numbers 26, 44 and 65 is divided by 1, itself and also by other numbers.
So 17 is a prime number whereas the 65, 26 and 44 are composite numbers.
