Find The quadratic Equation Whose Roots Are -2q And 5q.
3x\(^2\) + 3qx - 10q\(^2\)
x\(^2\) + 3qx + 10q\(^2\)
x\(^2\) - 3qx + 10q\(^2\)
x\(^2\) - 3qx - 10q\(^2\)
Correct answer is D
x\(^2\) - (sum of roots)x + (products of roots) = 0
x\(^2\) - (-2q + 5q) + (-2q * 5q) = 0
x\(^2\) -(3q) + (-10q\(^2\)) = 0
x\(^2\) -3q - 10q\(^2\) = 0

The height of an equilateral triangle of side is 10 3√ cm. calculate its perimeter.
20cm
60cm
40cm
30cm
Correct answer is B
Height of an equilateral triangle, h = a\(\frac{√3}{2}\), where a is the side of the equilateral triangle.
10√3 = a\(\frac{√3}{2}\)
cross multiply--> 2 * 10√3 = a√3
√3 strikes √3 on both sides
20 = a
The perimeter of an equilateral triangle is: P = 3a
P = 3 * 20 = 60cm
P = 30√3
