Solve for x: (x2 + 2x + 1) = 25
-6, -4
6, -4
6, 4
-6, 4
5, 5
Correct answer is D
x2 + 2x + 1 = 25
x2 + 6x - 4x -24= 0
x(x + 6) - 4(x + 6) = 0
(x - 4) - (x + 6) = 0
x = 4 or -6 = -6,4

In the diagram above, O is the center of the circle. If ∠POR = 114o, calculate ∠PQR
123o
118.5o
117o
114o
54o
Correct answer is A
Reflex POR = 2PQR
Reflex PQR = 360o - 114o = 246o
PQR = 246/2 = 123o
2.44cm
4.89cm
9.78cm
25.1cm
50.3cm
Correct answer is B
Circumference of circle = 2πr = 2 x 3.14 x 4
= 25.1cm 360o = 25.1cm
If logax = p, express x in terms of a and p
x = u + p
x = a/p
x = p
x = ap
x = ap
Correct answer is E
\(\log_{a} x = p\)
\(x = a^p\)
