Correct answer is B
by Pythagoras x2 = 62 + 82
36 + 64 = 100
x = \(\sqrt{100}\)
x = 10

8800cm2
8448cm2
4400cm2
4224cm2
Correct answer is A
L2 = 962 + 282
= 9216 + 784
= 10000
L = \(\sqrt{10000}\)
= 100cm
curved surface area = \(\pi r l\)
= \(\frac{22}{7} \times 28 \times 100\)
= 8800cm2
area of cone = area of sector
area of sector = 8800cm2
Given that (x + 2)(x2 - 3x + 2) + 2(x + 2)(x - 1) = (x + 2) M, find M
(x + 2)2
x(x + 2)
xv + 2
x2 - x
Correct answer is D
(x = 2)(x2 - 3x + 2) + 2(x + 2)(x - 1) = (x + 2)m
(m + 2)[(x2 - 3x + 2) + 2(x - 1)] = (x + 2)M
divide both side by (x + 2)
(x2 - 3x + 2) + 2(x - 1) = M
x2 - 3x + 2 + 2x - 2 = M
x2 - 3x + 2 + 2x - 2 = M
x2 - 3x + 2x = M
x2 - x = M
M = x2 - x
