23^(a+b)
Step-by-step explanation:
23^a x 23^b =23^(a+b)
Answer:
163.3m²
Step-by-step explanation:
area = Pi(r²)
r = d / 2
r = 12
12² = 144
144 x 3.14 = 452.16
diameter of bigger circle = 24 + 4 (2 on each side)
28 / 2 = 14
14² = 196
196 x 3.14 = 615.44
sidewalk = bigger - smaller
sidewalk = 615.44 - 452.16
sidewalk = 163.3
Answer: -5 * -5^n-1
Explanation: the equation for explicit formula is a (a 1 at the bottom of a) times r to the power of n minus 1
a with the 1 at the bottom just means your first term, which is -5.
R is Q which is -5
When you put that together you get -5 * -5^n-1
(The asterisk(*) means multiplication and the caret(^) means the variables and numbers after it are in exponent form.
Hope this helps!!
The answer is 60 because it can be divided by all three numbers. Next time you come across problems such as these, I suggest you start by looking at the number that makes sense logically. For instance, numbers that have 5 as a factor must end with 0 or 5, narrowing the options down to 65 and 60. Since 65 is an odd number, the answer can only be 60.
