Answer:

(1) x (x+ 3) - 4 (x +3) = 0

(2) x = 4 and x = -3

Step-by-step explanation:

given data

equation

(x−4)(x+3)=0

solution

given equation (x−4)(x+3) = 0

equation as a compound statement is

x (x+ 3) - 4 (x +3) = 0

and

two solutions to the equation are

so x (x+ 3) - 4 (x +3) = 0

x- 4 = 0 and x + 3 = 0

x = 4 and x = -3

If the circumference of a circle is about 15.4 cm, estimate to the nearest whole number the diameter of the circle

nasty-shy [4]

The nearest whole number the diameter of the circle is 5.0 cm.

<u>Given the following data:</u>

Circumference of a circle = 15.4 cm

To estimate to the nearest whole number the diameter of the circle:

In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.

<h3>How to calculate the circumference of a circle.</h3>

Mathematically, the circumference of a circle is given by the formula:

$Circumference = \pi D$

<u>Where:</u>

D is the diameter of a circle.

Making D the subject of formula, we have:

$D =\frac{circumference}{\pi}$

Substituting the given parameters into the formula, we have;

$D =\frac{15.4}{3.142}$

D = 4.90 cm

To the nearest whole number:

D = 4.90 ≈ 5.0 cm
