E^2x - e^x -56 =0
(E^x - 8) (e^x + 7) = 0
E^x - 8 = 0
E^x +7 = 0
X = ln8 or x = 2.07944154...
Assuming the other is equal to x, this would be a 30-60-90 triangle. This is because those angles must add to 90 degrees and one must be 2 times the second.
Answer:
Ok ive done that too, but my answer was B.
Step-by-step explanation:
Answer:
v = (base x height x length)/2
(7 x 10 x 13)/2 = 455 x 3.15 = 1433.25$
hope that answers your question
Answer:
-3
Step-by-step explanation:
4x - 5 + 2(x - 3) = 12x + 7
4x - 5 + 2x - 6 = 12x + 7
4x + 2x - 5 - 6 = 12x + 7
6x - 11 = 12x + 7
<em>collect like terms</em>
6x - 12x = 7 + 11
-6x = 18
-x = 3
x = -3
