if the length of a rectangle is 4 more than the width and if the perimeter 0of rectangle is 52, what is the width of the rectang
Ilia_Sergeevich [38]

Answer:15

Step-by-step explanation:

rectangle so we know two sides are equal and other two side are equal so we have X+X+X+4+X+4

so make it algerbra 4X+8=52

get rid of the 8 by subtracting from both side

4X+8-8=52-8

4X= 44

divide both sides by 4 to get rid of the 4

so X= 11

so two sides are 11

and two sides are 11+4 or 15

Determine the quadrant in which the terminal side of the given angle lies. -750°
Blababa [14]

Answer:

Quadrant 4

Step-by-step explanation:

If the given angle was positive, then we go clockwise.

But it's negative so we go counterclockwise.

An alternative way of graphing

Quadrant 1 is 0-90°

Quadrant 2 is 90-180°

Quadrant 3 is 180-270°

Quadrant 4 is 270-360°

Subtract the given angle by 360 until no longer possible

750 - 360 = 390     390 - 360 = 30

Remember that this was originally a negative angle

Instead of going clockwise to quadrant 1, we go counterclockwise to quadrant 4, ending up at 330°

Can u help me with (29,30,31)
Gennadij [26K]

Answer:

v = -5, t = -13. , d = -12

Step-by-step explanation:

29) 3v - 9v = 30

Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5.

30)12t - 8t = -52

Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13.

31) -8d - 5d + 7d = 72

Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.
