Combine like terms. Note that both have the same amount of variables

-5r - 3r = -8r

-8r is your answer

since they both have the same variables you can take them off and add them to the end of the answer so -5-3 =-8 then you can add the r at the end which would make -8r

A triangle has sides of lengths 12,14 and 19 . Is it a right triangle?
Scorpion4ik [409]

Answer:

It could be

Step-by-step explanation:

The calculation of sides of a rectangular triangle can be done by applying the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse), both legs must form a right angle, and the value of the hypotenuse must be different from the legs. In the example what you give could be a value of one leg and the other of the hypotenuse.

Two forces with magnitudes of 100 and 50 pounds act on an object at angles of 50° and 160°, respectively. Find the direction and
shusha [124]
Forces in direction x:
 
fx1 = 100 * cos (50) = 64.28
 fx2 = 50 * cos (160) = - 46.99
 The resultant is:
 fx = fx1 + fx2 = 17.29

 Forces in direction y:
 
fy1 = 100 * sine (50) = 76.60
 fy2 = 50 * sine (160) = 17.10
 The resultant is:
 fy = fy1 + fy2 = 93.70
 The magnitude of the resulting force is:
 
f = root (fx ^ 2 + fy ^ 2)
 f = root ((17.29) ^ 2 + (93.70) ^ 2)
 f = 95.28
 The angle is:
 
theta = atan (fy / fx)
 theta = atan (93.70 / 17.29)
 theta = 79.55 degrees
 Answer:
 
The direction and magnitude of the resultant force are:
 
f = 95.28 pounds at theta = 79.55 degrees
