Answer:
a^2b^2(18a^2-25b^2)^2 over 900
Step-by-step explanation:
Over 900 means that is a fraction
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!
==============================
For the second one, I think there are some words missing.
Answer:
-4
Step-by-step explanation:
The coefficient is the number that multiplies the variable.
To find the coefficient, you'll see it right next to the variable.
Here, x is the variable.
-4x, -4 is right next to x, so it's the coefficient
:)
The answer would be y=-13x+7
hope this helps ;]
