Answer:
<h3>
A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78</h3>
Step-by-step explanation:
H = 2x+6 - the hight
3H = 3(2x+6) - triple the hight
3H-5 = 3(2x+6) - 5 - five less than triple the height
Area of triangle: A = 0.5BH
B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13
H = 2x+6
So:
A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78
A = 6x² + 49x + 78
2+tan ×[-pi/4
2×10=20×16=[pi/320
11/12 divided by 3/4
11/12 • 4/3 (multiply by the reciprocal)
OR
Multiply from top to bottom
(11•4) • (12•3) = 44/36
Simplify (Divide top and bottom by the highest common factor... which in this case is 4)
