Answer:

(3x+2)(2x+3)

Step-by-step explanation:

Given the trinomial: $6x^2 + 13x + 6.$

We want to use the X Method to Factor the Trinomial.

a=6, b=13, c=6

The value of ac is 6*6=36
The value of b=13

Factors of 36 are:

1,2,3,4,6,9,12,18,36

Product of factors that gives 36 are:

1X36
2X18
3X12
4X9
6X6

The two numbers that have a product of ac (36) and a sum of b (13) are: 4 and 9.

Therefore our trinomial becomes:

$6x^2 + 13x + 6\\=6x^2 +9x +4x+ 6\\=3x(2x+3)+2(2x+3)\\=(3x+2)(2x+3)$

Thus, $6x^2 + 13x + 6$ in factored form is (3x+2)(2x+3)

How do you convert a mixed number 3 3/5 to an improper fraction?

oee [108]

Multiply 3 by the denominator, then add the numerator. Then we keep the original denominator.
So we get:
3 x 5 = 15 + 3 = 18
we get:
18/5

2^2/5+ 3^1/10 HELP ASAP

gizmo_the_mogwai [7]

Answer:

$\sqrt[5]{4}$ + $\sqrt[10]{3}$

Step-by-step explanation:

We sure can write 2^2/5+ 3^1/10 as $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$

// use the $a^{\frac{m}{n} } =\sqrt[n]{a^{m} }$ to transform the expression

Convert $2^{\frac{2}{5} }$ to $\sqrt[5]{2^{2} }$ = $\sqrt[5]{4}$ (here a = 2, n = 5, m = 2)

Then convert $3^{\frac{1}{10} }$ to $\sqrt[10]{3^{1} }$ = $\sqrt[10]{3}$ (here a = 3, n = 10, m = 1)

Now we get $2^{\frac{2}{5} } + 3^{\frac{1}{10} }$ = $\sqrt[5]{4}$ + $\sqrt[10]{3}$ . This is the simplified form, which is the answer.
