R = 36 because if you multiply 18 and 2, it gives you 36. If you check it to see if it's correct, then you would divide 36 by 2 to get 18.

A force of 3 pounds acts in the direction of 42 degrees to the horizontal. The force moves an object along a straight line from

EastWind [94]

Answer:

11.37 lb-ft

Step-by-step explanation:

We are given that

Force,F=3 pounds

$\theta=42^{\circ}$

Let Point A (3,7) and point B(8,8)

We have to find the work done by the force.

$d==$

$r=\mid d\mid=\sqrt{x^2+y^2}=\sqrt{5^2+1^2}=\sqrt{26}$ feet

We know that Work done by the force

$W=Frcos\theta$

Substitute the values

$W=3\times \sqrt{26}cos42=11.37 lb-ft$

Hence, the work done by the force =11.37 lb-ft

Solve for x<br> 3x + 6 over 3 = 6

Svetradugi [14.3K]

Answer:

X= 4

Step-by-step explanation:

3x+6/3=6

multiply each side by 3 to get rid of the fraction bar

3x+6=6*3

3x +6=18

-6 from both sides

3x= 18-6

3x=12

divide by three on both sides to solve for x

x=12/3

x=4
