Solve 3(x + 2) > x.​

Mathematics
1 answer:
Veronika [31]3 years ago
6 0

Answer:

<u>x > -3</u>

Step-by-step explanation:

This is an inequality, but it can be treated like a normal algebraic equation. You just need to isolate the variable. Here's a step-by-step:

3(x + 2) > x

Distribute the 3:

3*x + 3*2 > x

3x + 6 > x

Move the x to the right:

3x -x + 6 > x-x

2x + 6 > 0

Now, isolate the x by subtracting 6 from both sides:

2x + 6 - 6 > 0 -6

2x > -6

Finally, divide by the coefficient (2):

2x/2 > -6/2

<u>x > -3</u>

sp2606 [1]
Take the total cost of the meal ($32.92) and multiply it by 5% (.05)
once you multiply those together you get how much tax is which is $1.65 (rounded up from 1.646)
now add that to your total and you get $34.57.

What is the complete factorization of the polynomial below?
Hunter-Best [27]

The complete factorisation of the polynomial given; x³ + 2x² + 4x + 8 as in the task content can be factorised and determined as; Choice D; (x+2)(x+2i)(x-2i).

<h3>What is the complete factorisation of the given polynomial; x³ + 2x² + 4x+8?</h3>

It follows from the given task content that the polynomial whose factors are to be determined by means of factorisation is; x³ + 2x² + 4x+8.

It follows from observation that one of the zeros of the polynomial expression is at; x = -2.

Consequently, one of the factors of the polynomial in discuss is; (x+2).

x³ + 2x² + 4x+8 = (x+2) (x² - 4i²)

= (x+2)(x+2i)(x-2i)

Consequently, it follows that the complete factorisation of the polynomial is; (x+2)(x+2i)(x-2i).

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(8*32)

sqrt(256)

sqrt(16*16)

±16

The principle value is 16
