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.

Solve for b:<br><br> 6b+14 = -7-b
vladimir2022 [97]

Answer:

b = -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6b+14=−7−b

6b+14=−7+−b

6b+14=−b−7

Step 2: Add b to both sides.

6b+14+b=−b−7+b

7b+14=−7

Step 3: Subtract 14 from both sides.

7b+14−14=−7−14

7b=−21

Step 4: Divide both sides by 7.

\frac{7b}{7} = \frac{-21}{7}

b= -3

Answer:

Step-by-step explanation:

The formulas to find the x and y coordinates of E are:

x=\frac{bx_1+ax_2}{a+b}  and  y=\frac{by_1+ay_2}{a+b}  where x1, x2, y1, and y2 are from the coordinates of A and B, and a = 1 (from the ratio) and b = 2 (from the ratio). Filling in to find x first:

x=\frac{2(2)+1(-4)}{1+2}=\frac{4-4}{3}=0  and now for y:

y=\frac{2(-3)+1(9)}{1+2}=\frac{-6+9}{3}=\frac{3}{3}=1

The coordinates of E are (0, 1).

First, change the measurements of the pole to m so all of the units are the same.
41 cm=.41 m
72 cm=.72 m

Then, let x represent the height of the building

30/x=.72/.41
x=30*.72/.41
x=52.68 m
round to 52.7 m
