Factor this trinomial completely.

1 answer:

4 0

First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)

If 90 is 80 percent of the value what is the value

OLga [1]

If 90 is 80% of the whole value, then 1/4 of 90 added to 90 will be the value, because 1/4 of 80% (which is 20%) added to 80% will give us 100%

So,
90/4=12.5
90 + 12.5=102.5

At least, that's my take on it
