Answer:
x = - 4, x = 2
Step-by-step explanation:
Given
3x² + 6x - 24 = 0 ( divide through by 3 )
x² + 2x - 8 = 0 ← in standard form
(x + 4)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
Answer:
you have all of them right just make sure for number six you have 1/3125. you have all the work im not sure what i should solve.
For the main question, it's basically just the Pythagorean's Theorem, 400-144= 256, square root of 256 is 16, so it reaches 16 feet up the building.
For Picture 1: Another Pythagorean's Theorem question, since the two angles are both 45 degrees, then LM and KM are the same. They are both 5, so they both square to 25, added together 50. So we do square root of 50, and then you can change it to square root of 25 * square root of 2. And then you can change it to 5 * square root of 2.
Picture 2: isn't it the exact same?
Is it 25? because 25 divided by 2 is 50
