Total number paintings made by category of 7 children = 7*8 = 56
Total number of paintings made by the remaining = 3*12 = 36
Total number of paintings = 56+36= 92 paintings
Average number of paintings by all the children = 92/10 = 9.2 ≈ 9 paintings
The answer is d because
x²-36 = 0
x²-6² = 0
(x+6)(x-6) = 0
x = 6, -6
Using the Side Angle Side Formula
Area = ½ • side 1 • sine (A) • side 2
<span>Area = ½ • 12 * sine (63°) * 1.5
</span>Area = ½ • 12 * 0.89101 * 1.5
<span><span><span><span>Area = </span>8.01909
