Answer:
The answer to your question is: x = 5 units
Step-by-step explanation:
Data
AB = x - 2
BC = 2x + 6
AC = 19
x = ?
Process
AB + BC = AC
Solve for x, x - 2 + 2x + 6 = 19
3x + 4 = 19
3x = 19 - 4
3x = 15
x = 15 / 3
x = 5 units
Answer:
should be pretty similar to how a parabola looks
Step-by-step explanation:
as the length increases the area gets huge fast
For the subtracting fractions, I would just make them into improper fractions (examples: 6/4, 5/3). To do that, you multiply whole number by the numerator (number on top of fraction), then add the denominator (number at the bottom), and finally, leaving the denominator as is.
Then make them have the same denominator. you might have to multiply or divide in order to match the denominators. then you may add or subtract straight across. NEVER change the denominator.
note: you might be required to make the improper fractions into mixed (ex: 4 1/2)
With multiplying, just multiply across (numerator × numerator, and denominator × denominator)
Answer: 9
Step-by-step explanation:
Sorry the pi sign looks weird. The formula for area of a circle is 
, so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.
