Solve |x| < 13<br> A. {-13, 13}<br> B. {x| -13< x < 13}<br> C. {x|x < -13, x> 13}

Gemiola [76]

Answer:

the solution for x will be given by {x| -13 < x < 13}

Therefore the correct option is B.

Step-by-step explanation:

i) given that |x| < 13

ii) therefore x < 13 for positive values of x

iii) for negative values of x we have -x < 13

therefore x > -13

iv) from ii) and iii) above we can conclude that the solution for x will be given by {x| -13 < x < 13}

Therefore the correct option is B.

Bill and susan have ages that are consecutive odd integers.The product of their ages 438.Which equation could be used to find bi

zhuklara [117]

Answer:

4 $x^{2}$ + 8 x - 435=0

Step-by-step explanation:

Let x be any natural number

Let the age of Bill= 2 x+ 1 years (Since age is odd integer)

Than, age of a Susan= 2 x + 3 years

Since ages are consecutive odd integers

According to question

(2 x+1)(2 x+ 3)= 438

4 $x^{2}$ + 8 x + 3 = 438

4 $x^{2}$ + 8 x + 3 - 438 =0

4 $x^{2}$ + 8 x - 435=0

This equation can be used to find the ages of both

Hence, the correct answer is 4 $x^{2}$ + 8 x - 435=0
