Factorising
Factorise
5x + 10
5(x + 2)
Solve for x:
x + 5 = 16
x = 11
What is the length of the hypotenuse if the two shorter sides are 6cm and 8cm?
10cm
Area of a circle if the radius is 8cm (2 dp)
201.06cm2
Factorise
24x - 18
6(4x - 3)
Solve for x:
7x = 35
x = 5
What is the length of the hypotenuse if the two shorter sides are 9cm and 10cm? (2 decimal places)
13.45cm
Area of a circle if the radius is 4.5cm (2 dp)
63.62cm2
Factorise
x2 + 8x
x(x + 8)
Solve for x:
2x + 3 = 19
x = 8
What is the length of the missing shorter side if the hypotenuse if 12m, and one shorter side is 7.5m? (2 decimal places)
9.37m
Area of a circle if the diameter is 10cm (2 dp)
78.54cm2
Factorise
3x2 - 8xy
x(3x - 8y)
Solve for x:
5x - 8 = 52
x = 12
What is the length of the missing shorter side if the hypotenuse if 18m, and one shorter side is 10.1m? (2 decimal places)
14.90m
Area of a semi-circle if the radius is 9cm (2 dp)
127.23cm2
Factorise
5xyz + 10xy
5xy(z + 2)
Solve for x:
4x + 1 = 2x + 17
x = 8
