Answer:
21... 27.... 38...
Step-by-step explanation:
Add prime numbers to the number in alternate.
4 + 3 = 7
5 + 5 = 10
7 + 7 = 14
10 + 11 = 21
14 + 13 = 27
21 + 17 = 38
y = a(1 + r)ˣ
a = 15 "<em>initial" means what you started with on the first day</em>
r = 6 <em>the rate it increased is the slope (</em>
y = 15(1 + 6)ˣ
Answer: y = 15(7)ˣ
-5(2x+1)-2x-2=17
first, distribute
-10x-5-2x-2=17
combine like terms
-12x-7=17
get the x alone, eliminate the constant
-12x=24
divide out the -12 to get the x alone.
x=-2
The answer is 37/50......
Normal circle area is πr², which is (d/2)²π.
That makes your case 14²π divided by 2 is 196π/2=98π cm²
