The answer could be negative or positive. We are not given specific as to whether or not the starting number is positive or negative so therefore it could be either.
Hope this is helpful :)

Step-by-step explanation:
Multiply each ratio by the same number
4x3=12 7x3=21
Answer:
yes
Step-by-step explanation:
LMN should be a right triangle
use pythagorean theorem
18^2+80^2=82^2
it is a right triangle
9514 1404 393
Answer:
30°
Step-by-step explanation:
The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:
Sin = Opposite/Hypotenuse
For a ramp 1 m high and 2 m long, we have ...
sin(x) = (1 m)/(2 m) = 1/2
x = arcsin(1/2) = 30°
The elevation angle of the ramp needs to be 30°.
A) 3x+4=22
B) x=6
How to solve the equation: subtract 4 from both sides. You’re left with 3x=18. What is 18 divided by 3?
