Camila's favorite number is positive, and the square of her number plus twice her number

MaRussiya [10]

Answer:

Camila's favorite number is 4

Step-by-step explanation:

Hello, I can help you with this.

you can easily solve this by constructing a equation for the situation and then to find the unknown value.

Step 1

define

Let

x= the Camila's favorite

according to the problem.

Camila's favorite number is positive,so

X≥0

and

the square of her number plus twice her number is 24

$x^{2} +2x=24$

Step 2

$x^{2} +2x-24=0$

solve for x

using the quadratic equation

$x=-\frac{-b +-\sqrt{b^{2}-4ac } }{2a}$

a=1

b=2

c=-24

put the values into the equation

$x=\frac{-2 +-\sqrt{2^{2}-4(1)(-24)} }{2(1)}\\x=\frac{-2 +-\sqrt{4+96} }{2}\\\\x=\frac{-2 +-\sqrt{100} }{2}\\\\x=\frac{-2+10}{2} \\x=\frac{8}{2} \\x=4\\$

the second x in -6, it does not work because we are looking for a positive number so the answer is

Have a great day.

What is the best esimate for the following quotient <br>891.3÷28

arsen [322]

31.832142857 is what you got, look at your tenths digit. if it's greater or equal to 5, it will always round to the higher number. if its less than or equal to 4, it will be the lower number.

for example, 10.4 will be 10, as it is lower than 5

or 10.6 will be 11 cause it is higher than 5

adoni [48]

8500 you make two fractions set equal to eachother.. 6290/x (x is the missing number) and 74/100 (the percentage) you cross multiply the 6290 and 100 which is 629000 and divide it by the 74 which is 8500 which should be your answer
