Maths!!

1) Given that a rectangle with sides (2x + 2)cm and (x + 8)cm have an area of 88cm^2, determine the value of x.

2) Given that the area of a right-angled triangle is 120cm^2, determine the value of x. The height is 4x cm while the base is (3x + 3)cm.

2X^2 + 18X +16 - 88 = 0

Solve for roots of equation

( -18 +/- 30 ) / 4

X = 3

Is it not 3.37???

Hi,

The topic of algebraic equations may involve:

1. Forming an equation based on given information of a variety of contexts.

2. Solving the quadratic equation by factorisation, by the quadratic formula or by completing the square.

Thanks.
