Answer:
134.28 m²
Step-by-step explanation:
I suppose this is an isosceles triangle
tan 75° = 2 + √3 = 3.73 = h / 6 (h: height and 6 = 12/2, 1/2 of base)
h = 6 x 3.73 = 22.38
Area = (12 x 22.38) / 2 = 134.28
Answer:
x^2 + 2x - 8
Step-by-step explanation:
h(x) + k(x) = (2x^2 + 5x - 12) + (-x^2 - 3x + 4)
Add Like Terms
(2x^2 + 5x - 12) + (-x^2 - 3x + 4)
2x^2 - x^2 = x^2
(2x^2 + 5x - 12) + (-x^2 - 3x + 4)
5x - 3x = 2x
(2x^2 + 5x - 12) + (-x^2 - 3x + 4)
-12 + 4 = -8
x^2 + 2x - 8
Answer:
D- 38,430
Step-by-step explanation:
To find 18% of 213.5k, we need to convert 18% back into its decimal form (0.18), then multiply it by 213.5k and boom! there is your answer.
