The area of the cross section is in the shape of a triangle.
Answer:
x = 11√2
Step-by-step explanation:
We can notice the triangle given is a special triangle, a 45°- 45°- 90° triangle. The hypotenuse of a 45°- 45°- 90° is √2 times the length of a side. We can set up the equation(using x as the side):
x * √2 = 22
We can divide by √2 on both sides to get:
x = 22 / √2
To rationalize the denominator, we multiply by √2 / √2 on the right side:
x = 22√2 / 2
This simplifies to:
x = 11√2
Answer:
The answer to your question is: the last option 5a² + 3b + 6a
Step-by-step explanation:
7a² + 3b + 6a - 2a²
look for like terms
7a² - 2a² 3b 6a
Simplify like terms
5a² + 3b + 6a
Answer:
32 dollars for 8 pounds
Step-by-step explanation:
1. 2.5 times 3 = 7.5
2. 10 times 3 = 30
3. 2.5 divided by 5 = .5
4. 10 divided by 5 = 2
5. 7.5 + .5 equals 8
6. 30 + 2 = 32.
hope this helps you:)
