What is the answer for -(-(-(-2)))

2 answers:

8 0

-(-(-(-2))) is not a question, so it has no answer.

But if you'd like to clean it up and make it look less ugly, then
you should notice that there are 4 minus-signs operating on the '2'.
Every two minus-signs cancel each other, so 4 of them definitely
result in total annihilation of all the minus-signs, and the whole
revolting expression is equal to just 2 .

Make a conjecture about the next item in the sequence. 6, 9, 7, 10, 8?

inessss [21]

Answer:

"The next term should be 11"

Step-by-step explanation:

If we look closely at the sequence we can see:

second term is 3 more than previous

third term is 2 less than previous

fourth term is 3 more than previous

fifth term is 2 less than previous

We can see a pattern. To get next terms, we add 3, to get next to that, we subtract 2. It goes on like this.

Since 4th term to 5th term is "subtracting 2", logically 5th to 6th term (the term we are wanting) should be "add 3". So the term after 8 would be 11

The next term would be 11

Measure the screwdriver's length to the nearest tenth of a centimeter. Express the answer as a decimal.

Alja [10]

Answer:

17.1 cm

Step-by-step explanation:

A screw driver is a mechanical tool or device which is mainly used for screwing the screws and unscrewing them. It is also used for removing the nuts and bolts and also serves a variety of uses.

It is typically made of steel and has a handle and a shaft which ends as a tip.

In the context, the length of the screw driver from the given figure expressed to the nearest tenth of a centimeter is 17.1 cm.

It is also equivalent to $6\frac{3}{4}$ inch.

X^2+4x-1/(x+2)^2=0 solve for x

dalvyx [7]

x^2+4x-1/(x+2)^2=0
x^2 + 4x - 1 = 0

$\frac{x^2+10x-7}{x^2+10x+25} =0\\x^2+10x-7=0\\x= \frac{-b\pm\sqrt{b^2-4ac}}{2a}$ ;
where a = 1, b = 4 and c = -1

$x=\frac{-4\pm\sqrt{4^2-(4\times1\times(-1)}}{2\times1}\\=\frac{-4\pm\sqrt{16+4}}{2}=\frac{-4\pm\sqrt{20}}{2}\\=\frac{-4\pm\sqrt{4\times5}}{2}=\frac{-4\pm2\sqrt{5}}{2}=-2\pm\sqrt{5}\\=-2+\sqrt{5}
 \ or \ -2-\sqrt{5}\\x=0.24 \ or \ x = -4.24$
