The length of a rectangle is 4 units more than triple its width. If the perimeter is 64,
what is the length of the rectangle?

Answers

Answer: Length = 25, width = 7

Step-by-step explanation:

Let width be w, and length be 3w + 4.

Perimeter of a rectangle = 2l + 2w

                                 64  = 2(3w + 4) + 2w

                                 64  = 6w + 8 + 2w

                                 64  = 8w + 8    [subtract 8 from both side]

                                 56  = 8w          [Divide 8 from both side]

                                  w   = 7

Plug w in l, where l = 3w + 4 = 21 + 4 = 25

Answer:

See answer below.

Step-by-step explanation:

   there because this is your starting point.

2.  Move to the left over to point -1 3/4 . This place is between -1 and -2, and

     closer to -2 because the point is -1 .75.  Remember this point is not on the

     graph.  

3.  Now move up from that point to 4.5 and put a dot at that place.  The point is in the Q II ,  to the left top.

Step-by-step explanation:

Answer:

x = 12.633, -0.633

Step-by-step explanation:

x^2 -12x + 36 = 44

the underlined part is (x - 6) ^2

(x - 6)^2 = 44

(x - 6) = ± [tex]\sqrt{44}[/tex]  (both positive and negative)

(x - 6 ) = + 6.6332495807108

x = 12.6332495807108 = 12.633

(x - 6 ) = - 6.6332495807108

x = - 6.6332495807108 + 6

= -0.6332495807108 = -0.633

five more than one-third of a number is -2. Find the number

Answers

Answer:

x = -21

Step-by-step explanation:

Words To Algebra:

Words : Five more than one-third of a number = -2

Algebraic Equation: 5 + (1/3)x = -2

Isolate x:

5 + (1/3)x = -2      [tex]\longmapsto\\[/tex]    Subtract 5 from both sides

5 + (1/3)x - 5 = -2 - 5

(1/3)x = -7     [tex]\longmapsto\\[/tex]     Multiply All sides by 3

(1/3)x * 3 = -7 * 3

x = -21

Check:

5 + (1/3)-21 = -2

5 + -7 = -2

-2 = -2
