Answer:

No. It would be (x + 5)

Step-by-step explanation:

set each of the factors as equal to 0. So if you do x+5=0 then solve for x by subtracting 5 from both sides you get x = -5

The clue is to switch the sign from the factor to get the value of the variable and vice-versa.

I have 2 questions to ask 1 is divide 180 degrees in a ratio of 4,5 and 9

MAXImum [283]

Here's how to do dividing in a certain ratio:

-- You want to divide up the whole thing in the ratio of
4 parts, 5 parts, and 9 parts.

-- How many parts all together ? (4 + 5 + 9) = 18 parts all together.

-- The whole thing is 180, and that's 18 total parts.
So each part is (180/18) = 10 degrees.

4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.

Check: (40 + 50 + 90) = 180 . yay!
