Solve k^2 + 13k + 30 = 0

kogti [31]

K² + 13k + 30 = 0

This is a quadratic equation. Let's attempt solving it by factorization.

Coefficient of k² = 1, last term = 30

Multiply these two together 1*30 = 30

We think of two numbers that multiply to give 30 and add to give the middle term 13.

The two numbers are 3 and 10.

3*10 = 30, 3 + 10 = 13.

we replace the 13k with 3k + 10k

k² + 13k + 30 = 0

k² + 3k + 10k + 30 = 0

k(k + 3) + 10(k + 3) = 0

(k + 3)(k + 10) = 0

(k + 3) = 0 or (k + 10) = 0

k = 0 - 3 or k = 0 - 10

k = -3, or -10

Are the fractions 3/9, 3/10, 3/11, and 3/12 in order from least to greatest

Cerrena [4.2K]

Answer:

The fractions $\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$ are not in order from least to greatest.

Step-by-step explanation:

Given order of fractions from least to greatest:

$\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$

To check if the fractions are in correct order.

Solution:

The fractions given have same numerators but different denominators.

For fractions the higher the denominator the lower is the value of that fraction.

Thus, in the given list the least value fraction will be the fraction with the greatest denominator which is $\frac{3}{12}$ and the greatest value fraction will be the fraction with the least denominator which is $\frac{3}{9}$
