they all need to have '' ( ) '' in them.

if a number is outside of that, it needs to at least have a letter beside the number

here's an example

Factored form:

2x(x + y)

not factored:

2(x - y)

but for the first one, it's correct from the rest of them.

She purchased 40% of the copies in the store. She has 80 copies of the cd. How many cd were on sale
mafiozo [28]
To find the number of CD on sale, we can set an equation.

Let y be the number if CD.

As she bought 40%, the amount she bought= 40%y

The equation:

40%y = 80

0.4y = 80

y = 80÷0.4

y=320

Therefore there were originally 320 CDs.

Hope it helps!

MArishka [77]

Answer:

(3x3−6x2+7x−11)+(10x2−9x+4) = 10-2x

13x3−15x+7x−7 = 32-8x

3x3+4x2−2x−7 = 10-2x

3x3+4x4−2x2−7 = 14

(12x2−7x+8)−(4x2−5x+10) = 14-2x

16x2−12x+18 = 50-12x
