Can you help me with a maths assignment please?

Question

Given that a=6 , b=-4 and c=8, calculate the value of 

a2square + b

     c -b

Solve these inequality

1. x - 3     <   3x - 7

2. 3 - 2 x < 7

Simplify the expression:

3( x - y) + 4(x +2y)

4x(2square) multiple by 3x (4square)

                   6x (3square)

 

Factorize completely

(i) x 2 square - xy

(ii) a 2 square - 1

Answer 1

(a^2 +b) / (c-b) & a=6, b=-4, c=8

c-b=8- (-4)=8+4=12

a^2=6^2=36

a^2+b=36-4=32

anser=32/12=2.66666

Answer 2

a2square + b

     c -b         Would be transferred to 6 x 2squared +4 / 4.

Solve these inequality

1. x - 3     <   3x - 7  Correct.

2. 3 - 2 x < 7 Correct.

Simplify the expression:

3( x - y) + 4(x +2y)  

4x(2square) multiple by 3x (4square)

                   6x (3square)

 This would be transferred to 4 x 2squared x 3 times "x" 4^2.

Factorize completely

(i) x 2 square - xy

(ii) a 2 square - 1
