Answer:
-mn² - 10m²n.
or
-mn(n + 10m).
Step-by-step explanation:
mn²- 2m²n-8m²n - 2mn²
Bring like terms together:
= mn² - 2mn² - 2m²n-8m²n
= -mn² - 10m²n.
You can also factor this
= -mn(n + 10m)
Use the information to form a ratio... 6:8 or 6/8. Now set it equal to a ratio per 100...
6/8 = x/100
Cross multiply
8x = 600
x = 600/8
x = 75
75% have moons
Which what ? There are no choices to pick anything from.
If we can massage the equation to get ' y ' all alone on one side and everything else on the other side, then we can read the slope and y-intercept right from the equation. Let's do it.
You said
y - 3 = x + 6
Add 3 to each side:
y = x + 9
And there we have it.
The graph is a straight line. Its slope is 1, and it crosses the y-axis at the point where y=6.

In problems like this, it always helps to draw a picture.

Now, the trigonometric function tangent can be found with opposite / adjacent
When looking at ∠D, the opposite side if 48 and the adjacent side is 55.
O / A = 48 / 55
If the length is two times its width and its perimeter is 36cm. we can write the following equation
let the width be X.
so the equation will be:
(X + 2X)2=36cm or
2X + 4X=36cm
