The equation A = x(x-4) describes the area, A, of a rectangular flower garden, where x is the width in feet.

Answer:

The flower garden width would be 6 ft

Step-by-step explanation:

A = 12 ft^2 = x(x + 4) becomes:

x^2 + 4x - 12 = 0, or (by completing the square) x^2 + 4x + 4 - 4 - 12 = 0

Thus, we have (x + 2)^2 - 16 = 0, or (x + 2)^2 = 16

Taking the square root of both sides yields x + 2 = ±4.

In this context only a positive x value makes sense:  x = 2 + 4  =>  x = 6.

The flower garden width would be 6 ft.  The other dimension would be 6 - 4, or 2, ft.

MAVERICK [17]

Answer:

The answer to your question is below

Step-by-step explanation:

1.- Find the volume of the cylinder

Data

diameter = 9 cm

radius = 4.5 cm

height = 15 cm

Formula

   V = πr²h

   V = π(4.5)²(15)

  V = 303.75π         This is te answer for the volume in terms of π

       = 952.78 cm³                

2.- Find the volume of the cylinder

height = 40 yd

radius = 12 yd

Formula

   V = πr²h

   V = π(12)²(40)

   V = 5760π              This is te answer for the volume in terms of π

       = 18086.4 cm³

3.- What is the height .......

height = q

side length = r

4.- Volume of a pyramid

    Volume = Area of the base x height

Area of the base = 11 x 11 = 121 cm²

    Volume = 121 x 18

   Volume = 2178 cm³

Rachel was an 85 average after four test. what does she need to earn on the next test if she wants to raise her average to exact
irakobra [83]

she took four tests with one more to take totals 5 tests

 88 x 5 = 440

 all her tests need to equal at least 440 to get an 88 average

since she has 85 average after 4, 85*4 = 340, so her 4 tests so far have equaled 340

440-340 = 100

 she will need to get a 100 on her 5th test to have an 88 average
