Work shown above! x = 7
To solve use the supplementary angle next to the unknown angle to find an expression for that unknown angle and use that with the expressions inside the triangle to set equal to 180 and solve for x.

How do I simplify ((3x^2+12x+12)/(2x^2+x-6))/((4x^2-9)/(3x^3+x^2-10))

Shalnov [3]

$\dfrac{ \frac{3x^2+12x+12}{2x^2+x-6} }{ \frac{4x^2-9 }{3x^3+x^2-10} } =$

$= \dfrac{3(x + 2)^2}{(2x - 3)(x + 2)} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)}{2x - 3} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)(3x^3+x^2-10) }{(2x - 3)^2(2x + 3)}$

Starting with number 0 on my calculator, I do a calculation in five steps. At each step, I either add 1 or multiply by 2. What i

alisha [4.7K]

Answer:

assuming only positive integers, the answer is 1

Step-by-step explanation:

the smallest number that you can get by adding is:

start with 0
then add 1 = 1
add another 1 = 2
add another 1 = 3
add another 1 = 4
add another 1 = 5

but you can also multiply, and anything multiplied by 0 is 0:

start with 0
multiply by 2 = 0
multiply by 2 = 0
multiply by 2 = 0
multiply by 2 = 0
multiply by 2 = 0

The question does not say that we need to do any specific calculation, it only gives us 2 options and we can choose them as many times as we want.

Round 62,686 to nearest hundredth

Semenov [28]

Answer: 62.7 is rounded to the nearest hundredth.

Step-by-step explanation:

Because...

if you look at the 6 at the hundredth place then you have to look at the number next to it, which is 8 and since it's 5 and greater it the 6 becomes a 7 and therefor, the answer is 62.7.

* Hopefully this helps:) Mark me the brainliest:)!!
