El número decimal 1,3 lo expresamos en fracción como 13/10

El inverso de esa fracción es otra fracción pero los números de arriba y abajo se intercambian

→ El inverso de 13/10 es 10/13

Ahora hacemos la suma

\frac{13}{10} + \frac{10}{13}

\frac{13\cdot 13+ 10 \cdot 10}{10\cdot 13}

\frac{169+ 100}{130}

\boxed{\frac{269}{130}}

El valor decimal

\boxed{2,0\overline{692307}}

PLEASE ANSWER I WILL MARK THE BRAINIEST ANSWER :)<br><br>factorise: X^2 + 10x + 16
Damm [24]

Answer:

(x+2)(x+8)

Step-by-step explanation:

1.)find factors of the third expression(16)that will add up to give the second expression(10)

16=2×8. 10=2+8

2.)substitute those factors inplace of 10

{x}^{2}  + 10x + 16

x {}^{2}  + 2x + 8x + 16

3.)factorise using grouping method

( {x}^{2}  + 2x) + (8x + 16)

x(x + 2) + 8(x + 2)

= (x + 2)(x + 8)

Papessa [141]
<span>x cubed +3x squared - 4x= 0
= x^3 + 3x^2 -4x = 0
=x(x^2 +3x -4) = 0
= x (x+4)(x-1) = 0

x = 0
x+ 4 = 0 then x = -4
x - 1 = 0 then x = 1
answer: x = 0, x = -4 and x = 1</span>
