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
(b) Solve the inequality and write the solution set.
(c) Graph the solution on a number line.
a)5x3
b)9x3
c)5x3 – 8x2
d)9x3 – 8x2
