Answer:

Step-by-step explanation:

The correct divisor is 2. You change the sign of the real number without a variable when that real number is the divisor.

So - 2 becomes 2 and C and D are both incorrect.

The 0 comes between - 2 and 4 because the x term is 0x. (there isn't one).

That makes B wrong.

The answer is A

Which term is correct when simplifying √128? A.) 16 B.) 12 C.) 10 D.) 8√2

alina1380 [7]

When dealing with roots, we want to factor to see if it's possible

$128 = 2 \times 64$
$= 2 \times 2 \times 32$
$= 2 \times 2 \times 2 \times 16$
$= 2 \times 2 \times 2 \times 2 \times 8$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 4$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2$

now since we're dealing with square roots, we circle every pair of numbers we see in the final factoring
so..
$= (2 \times 2) \times (2 \times 2) \times (2 \times 2) \times 2$

now for every circled pair, we take only 1 of the 2 circled and bring it outside
anything left uncircled stays inside the root
so..
$= 2 \times 2 \times 2 \times \sqrt{2}$

now simply multiply
$8 \sqrt{2}$

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Masteriza [31]

Answer:

For the box that you did not fill out the area of that shape is 190 sq units

Step-by-step explanation:

10 x 5 = 50 ÷ 2 = 25

10 x 15 = 150

10 x 3 = 30 ÷ 2 = 15

25 + 150 + 15 = 190

24 written as a percentage

Yanka [14]

Any number is equal to that number over 1

So x is equal to x/1

Same thing with 24. 24 = 24/1

To get it into percent we multiply by 100 so:

$\sf{\frac{24}{1}=\frac{24\times100}{1\times100}}$

And simplifying that we get

$\sf{\frac{2400}{100}}$

And x/100 = x%

so 2400/100 = 2400%

So your answer is 2400% :)
