Answer:
11/4
Step-by-step explanation:
Multiply the denominator by the whole number and add it to the numerator and keep the denominator the same therefore it would be 11/4.
D. I think it that answer because it not close to 1
Answer:
Option A is correct.
The equation = .
Explanation:
Sum of the terms of an arithmetic series is given by
, ......[1]
where n is the number of terms, is the first term and is the last term.
Given the formula for nth term in the arithmetic sequence is,
for n =1
for n =9
Then, put these values in equation [1] for n =9;
or
Therefore, the equation is;
X² + 3x = 10
Convert to standard form.
x² + 3x - 10 = 0
factor x² = x * x
factor -10 = 5 * -2
(x + 5) (x - 2) = 0
x(x -2) + 5(x-2) = 0
x² - 2x + 5x - 10 = 0
x² + 3x - 10 = 0
x + 5 = 0 x² + 3x = 10
x = -5 -5² + 3(-5) = 10
25 - 15 = 10
10 = 10
x - 2 = 0 x² + 3x = 10
x = 2 2² + 3(2) = 10
4 + 6 = 10
10 = 10
