<h2>Explanation:</h2>
To find the area of the shaded region, we must find the area of the inner white triangle and subtract it from the area of the outer blue one.
Outer:
A =
bh
A =
(12 · 5)
A =
(60)
A = 30 mm²
Inner:
A =
bh
A =
(4 · 3)
A =
(12)
A = 6
30 - 6 = 24
A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x.
Let d = discriminant
d = b^2 - 4ac
Let a = 2, b = 4 and c = -9
We now plug and chug.
d = (4)^2 - 4(2)(-9)
d = 16 - 8(-9)
d = 16 + 72
d = 88
Basically, the distance of roots to the axis of symmetry are the same to each other. Other root is -5.6. Hope this help.
