Find the dimensions of the rectangle
hoa [83]
(a) The sum of length and width is half the perimeter, so the breadth in terms of length (x) in cm will be
.. breadth = 34 -x


(b) Then the expression for the area (in cm^2) is
.. area = length*breadth
.. 253 = (x)(34 -x)
.. x^2 -34x +253 = 0 . . . . . subtract the right side, eliminate parentheses
.. (x -11)(x -23) = 0 . . . . . . . factor
.. x = 11 or 23

The dimensions of the rectangle are 11 cm by 23 cm.

Find the circumference and the area of a circle with diameter equal to 8.6 inches. Use 3.14 for pi
mariarad [96]

Answer: Circumference of circle = 27.004 inches

              Area of circle = 58.0586 inches²

Step-by-step explanation:

Diameter of circle = 8.6 inches

Pi (\pi) = 3.14

Circumference of circle (With diameter) = \pi \\d (\pi×diameter)

                                                                = 3.14 × 8.6

                                                                = 27.004 inches

Area of circle (With diameter) = \pid^{2}/4

                                                 = 3.14 × 8.6 × 8.6 / 4

                                                 = 3.14 × 73.96 / 4

                                                 = 58.0586 inches²

Does someone know how to do this?
amid [387]

3√x+2 = √x+4

divide both sides by 3

√x+2 = √x+4 / 3

remove radical by squaring both sides

x+2 = x+4/9

x+2 = x/9 + 4/9 =

8x/9 = -14/9

8x*9 = -14*9=

72x = -126

x = -7/4
