Factorise Following

a)3a + 15 ( is it: 3a + 15 = 3 x a + 3 x 5 = 3(a+5)

b)4 x – xy + 3x2

Solve Following

a)2n + 3 = 17

b)3x – 4/2 – 6 = 4

c)5(x – 2) = 4 (x + 9)

But this particually, I can’t get:

a) The adjacent sides of a rectangle are (3x – 8) and 6 cm.

Given that the area of the rectangle is 96 cm^2, find the length of the rectangle and the value of x.

c)The Three sides of a triangle are 1/1 y + 2 and y = 4. The perimeter is 87 cm. What are the lengths of the three sides?
