Correct answer is D
let the number of question = n
n(n + 50) = 600
n2 + 50n - 600 - 0 by quadratic formular
x = \(\frac{b \pm \sqrt{b^2 - 4ac}}{2}\)
n = \(\frac{-50 \pm \sqrt{50^2 - 4(1) (-600)}}{2(1)}\)
= \(\frac{-50 \pm \sqrt{4900}}{2}\)
= \(\frac{-50 + 70}{2}\)
= \(\frac{20}{2}\)
= 10
11cm
18cm
21cm
34cm
Correct answer is A
volume of rectangular container = L x B x H
1 litre = 1000cm3
96 litres = \(\frac{1000cm^3}{1 litres}\) x 96 litres
volume = 96000cm3
96000 = 220 x 40
96--- = 8800H
H = \(\frac{96000}{8800}\)
= 10.97cm
= 11cm
230m2
231m2
232m2
233m2
Correct answer is D
A = L x B
= (18.6 x 12.5)m2
= 232.5m2
= 233m2
on one of the vertices
at a midpoint of a side
inside the triangle
outside the triangle

Find the smaller value of x that satisfies the equation x2 + 7x + 10 = 0
-5
-2
2
5
Correct answer is A
x2 + 7x + 10 = 0
x2 + 5x + 2x + 10 = 0
x(x + 5) + 2(x + 5) = 0
(x + 2)(x + 5) = 0
x + 2 = 0 or x + 5 = 0
x = -2 or x = -5
the smaller value x = -5x2 + 7x + 10 = 0
x2 + 5x + 2x + 10 = 0
x(x + 5) + 2(x + 5) = 0
(x + 2)(x + 5) = 0
x + 2 = 0 or x + 5 = 0
x = -2 or x = -5
the smaller value x = -5
