Blababa [14]

Answer: 6 eggs

Step-by-step explanation:

Given : The number of eggs required for the original recipe of muffins = 3

If the number of people coming to the meeting has doubled, then the number of eggs you need to make twice as many muffins will be the product of 2 and 3.

i.e.  The number of eggs you need to make twice as many muffins = 2\times3=6

Hence, you need 6 eggs to make twice as many muffins.

A = 360 cm^2

Step-by-step explanation:

Using Pythagorean theorem, the length AB is given by

AB^2 = 17^2 - 8^2 = 225 cm^2

or

AB = 15 cm

Since the ratio BC: CD = 1:2 and BC = 8 cm, this means that CD = 2×(8 cm) = 16 cm

so the length BD is

BD = BC + CD = 8cm + 16 cm = 24 cm

There the area of the rectangle is

A = AB×BD

= 15cm×24cm

= 360 cm^2

b) fraction on the right-hand side.

Critical

that the denominator can not be equal to zero

Step-by-step explanation:

When solving a polynomial inequality by hand, the solutions of the associated equation are called the Critical or Key numbers. These numbers divide up the number line into regions that contain or do not contain the intervals which satisfy the inequality.

b. When solving a rational inequality by hand, the solutions of the associated equation as well as values that make the fraction on the right-hand side of the rational expression zero are called the Critical numbers. The restriction of a rational expression is that the denominator can not be equal to zero included (Undefined)included in the solution set.
