### (Homework) Generalising: From Numbers to Algebra

This TASK is

To be completed by Sunday (23 Feb 2014)

Attempt the following:

**COMPULSORY**.To be completed by Sunday (23 Feb 2014)

Attempt the following:

### Algebra... Which is larger? (I)

Which is larger in magnitude?

**5 + n**or

**5n**

Explain your answer clearly with examples.

Enter your response in Comments.

### Algebra... Which is larger? (II)

Jennifer says, "

*. "*

**5x**^{2}is always smaller than (-5x)^{2}**Do you agree? Explain your answer.**

Enter your response in Comments.

This question is compulsory.

### Algebra... Help! What's Wrong?

Jane did the following:

**3a + b = 3ab****2s + 4t = 6st**

Do you think Jane is correct in her algebraic manipulations?

If yes, please write down examples to show that her answer is correct.

If not, explain to Jane her mistakes and help her to correct.

*Enter your response in Comments.*

### Algebra... Different "Faces" of Algebra (I)

The total length of 4 roads is (3x - 1) km.

What are the possible lengths of the 4 roads in kilometres?

Enter your suggested lengths in comments.

What are the possible lengths of the 4 roads in kilometres?

e.g. The length of the 4 roads are:

**x km, x km, x-7 km, 6 km**
Check:

**x + x + (x - 7) + 6 = 3x - 1**Enter your suggested lengths in comments.

### Algebra... Different "Faces" of Algebra (II)

The perimeter of a rectangle is (6x + 5y) cm.

Enter your suggested dimensions in Comments

Suggest 2 possible dimensions of the rectangle.

e.g.

Length of rectangle = 2x + 2y cm

Breadth of rectangle = x + 0.5y cm

Check:

Perimeter = 2 (2x + 2y) + 2 (x + 0.5y) cm

= 4x + 4y + 2x + y cm

= 6x + 5y cm

Enter your suggested dimensions in Comments

### Algebra: Equation vs Expression

**(I) Algebraic Expressions vs Equations**

The following are

**expressions**

**3***x***5 - 2***y**p*+ 2*q*- 45**mn**

**equations**:

**2***x*= 4*x*+ 8 = 20*x*² = 36**2***x*+*y*= 4

*Can you tell the difference between an expression and an equation?***(II) Coefficients, Variables and Constants**

In the following algebraic expressions:

(a) 6

*x*

*x*is a variable- 6 is the coefficient of
*x* - There is no constant

*y*+ 5

*y*is a variable- 2 is the coefficient of
*y* - 5 is the constant

*m*+ 7

*n*+ 9

*m*and*n*are variables- 3 and 7 are coefficients of
*m*and*n*respectively - 9 is the constant

*p*+ 2

*q*- 45

*p*and*q*are variables- 1 and 2 are coefficients of
*p*and*q*respectively - -45 is the constant

*a -*3

*b +*1

*a*and*b*are variables- 5 and -3 are coefficients of
*a*and*b*respectively - 1 is the constant

*x*-

*y*

*x*and*y*are variables- 1 and -1 are coefficients of
*x*and*y*respectively - There is no constant

**When given an expression, are you able to pick out the variable(s), coefficient(s) and constant terms?**Click HERE to read more about these...

**Let's learn more terms that are related to Algebra through the**(select "Algebra")
