I have some notes here that will help you answer the problem on your own:

Working rules for finding particular terms:

Step 1:

Find the general term Tr+1 in the expansion of (a + b)n.

Step 2:

Assume that Tr+1 is the desired particular term.

Step 3:

Find the value of r.

Step 4:

Put the value of r in the term Tr+1. This gives the required particular term(s).

I hope my answer has come to your help. God bless and have a nice day ahead!

Jordan is cutting a 2 meter by 1 1/4 meter into two pieces by its diagonal line

Airida [17]

Question:

Jordan is cutting a 2 meter by $1\frac{1}{4}$ meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?

Answer:

Area of each piece of paper is $1 \frac{1}{4} \ m^2$ .

Solution:

Length of the paper = 2 m

Width of the paper = $1\frac{1}{4}$ m = $\frac{5}{4}$ m

<em>Area of the rectangle = length × width</em>

$$=2\times \frac{5}{4}$

$$= \frac{5}{2} \ m^2$

<em>Diagonal of a rectangle divides it into two equal parts.</em>

Area of each piece = Area of the rectangle ÷ 2

$$=\frac{ \frac{5}{2}}{2}$

$$=\frac{5}{4} \ m^2$

$$=1 \frac{1}{4} \ m^2$

Area of each piece of paper is $1 \frac{1}{4} \ m^2$ .

Today, George is three times as old as his sister Lucy. In two years, Lucy will be half as old as George, How old will George be

saw5 [17]

Answer:

In two years, George will be 8 years old.

Step-by-step explanation:

g = 3s

(g + 2) / 2 = a + 2

g + 2 = 2 (s + 2)

g + 2 = 2s + 4

g = 2s + 2

3s = 2s + 2

s = 2

g = 3s

g = 3 (2)

g = 6

6 + 2 = 8
