There are 25 balls. The chance of getting one of the ten red balls is 10/25. 10 divided by 25 is .2, which in percent form is 20%. I hope this helped!

Assuming 18cm is the height (depth) then you have just 3cm more to fill to top.

volume = 26cm x 20cm x 3 cm = 1,560 cm cubed or 1,560 ml

(x²+x+1)+(-2x² 3x+5)
ExtremeBDS [4]

Step one: (((x2)+x)+1)+((0-(2x23•x))+5)

Step two: Check for a perfect cube.  2.1    -2x24+x2+x+6  is not a perfect cube.

2.2      Factoring:  -2x24+x2+x+6

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  x+6

Group 2:  -2x24+x2

Pull out from each group separately :

Group 1:   (x+6) • (1)

Group 2:   (2x22-1) • (-x2)

The groups have no common factor and can not be added up to form a multiplication.

So the answer would be,  -2 (x24) + (x2) ++ 6.

What is the answer please -16-1x=-4x+8
Alisiya [41]

-16-1x = -4x +8

add 1x to each side

-16 = -3x +8

subtract 8 from each side

-24 = -3x

divide both sides by -3

x = -24 / -3 = 8

x = 8
