Answer:
-4 and -3.
Step-by-step explanation:
Let the numbers be x and x+1.
From the given information:
x^2 + (x + 1)^2 + x = 21
x^2 + x^2 + 2x + 1 + x - 21 = 0
2x^2 + 3x - 20 = 0
(2x - 5 )(x + 4 ) = 0
x = 5/2 or -4 We ignore 5/2 as its not an interger
So the required integers are -4 and -3.
Answer:
16767
Step-by-step explanation:
Each new term is found by multiplying the previous term by 3. Thus, 3 is the common ratio. The formula for this geometric series is therefore
a(n) = 23*3^(n - 1).
The 7th term is a(7) = 23*3^6 = 16767

100 * 0.75 / 15 = 5
0.75 is 15%
X Is 100%
Then you draw diagonal lines:
0.75 times 100
Then divided by 15 equals
