40,000 cause 4x10 is forty and then add the zeros
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
sin²Θ = 1 - cos²Θ , cos²Θ = 1 - sin²Θ
Consider the left side
(sinΘ + cosΘ)(1 - sinΘcosΘ) ← distribute
= sinΘ(1 - sinΘcosΘ) + cosΘ(1 - sinΘcosΘ)
= sinΘ - sin²ΘcosΘ + cosΘ - sinΘcos²Θ
= sinΘ - (1 - cos²Θ)cosΘ + cosΘ - sinΘ(1 - sin²Θ)
= sinΘ - cosΘ + cos³Θ + cosΘ - sinΘ + sin³Θ ← collect like terms
= sin³Θ + cos³Θ
= right side ⇒ proven
Its radical 49 :) (by radical 7 means square root of 7)
Answer:
The missing side length is 36
Step-by-step explanation:
You need to find the ratio of the dilation so if you take corresponding sides, for example, 72 and divide by 8 you get 9. So, if you multiply each side of the triangle XYZ by 9, it should get the length of the sides on triangle ABC.
4 * 9 = 36
Hope this helps! :)
-x = 4 -3x + 6
First, let's get x on one side.
Add 3x to both sides.
-x + 3x = 2x
-3x + 3x = 0
We now have:
2x = 4 + 6
Combine like-terms (add 4 to 6)
4 + 6 + 10
2x = 10
Divide both sides by 2 to solve for x.
2x / 2 = x
10 / 2 = 5
We're now left with:
x = 5
I hope this helps!
