Use the Pythagorean Theorem of a² + b² = c² to solve for x.
x² + (x + 3)² = (√117)²
x² + x² + 6x + 9 = 117
2x² + 6x + 9 = 117
2x² + 6x + 9 - 117 = 0
2x² + 6x - 108 = 0
2x² + 18x - 12x - 108 = 0
2x(x + 9) - 12(x + 9) = 0
(2x - 12)(x + 9) = 0
x = - 9, 6
Length cannot be negative so you can't use - 9.
x = 6. Option C is your answer.
Answer:
Step-by-step explanation:
Cross multiplying, we have,
Integrating both sides,
We obtain,
, where C is the constant of integration.
We know that y(0) = 4
Putting these value in the above equation, we get C =
Thus,
Answer:
22 inches?
Step-by-step explanation:
Cause the question stated the height is 22 inches ?
Answer:
Poop
Step-by-step explanation:
That is found by applying the Pythagoras Theorem. ( 4 up and 3 to left then joining the points forms a right angled triangle).
x^2 = 3^2 + 4^2 = 25
x = 5 units (answer)
