Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.
So our equations to test for are:
![-r-3>-6\\-r+3](https://tex.z-dn.net/?f=-r-3%3E-6%5C%5C-r%2B3%3C6%5C%5Cr%2B3%3C6%5C%5C-r%2B3%3E6)
We can input 18 as r and then we see the following are correct:
1. No, as a -21 is not greater than -6
2. Yes, as -15 is less than 6.
3. No, as 21 is not greater than 6
4. No, as -15 is not greater than 6.
Cheers!
Answer:
16
Step-by-step explanation:
8+8=16
Area of the bases
<span>2π<span>r2</span>=2π∗784=1568π
</span>circumference of base
<span>2πr=56π
</span>extension of the height
<span>2πr∗h=56π∗48=2688π
</span>bases plus none base surface is total surface
<span><span>1568π+2688π=4256π</span></span>
B. D represents the amount of dimes and q represents the amount of quarters so that equals 20 coins total. 0.25q is the amount of quarters multiples by their cost, when added to 0.1d it equals 4.25.
