A. 10 feet.
Think of it like this:
The wall is upright, it's 90° and it's 8 feet high. The distance from the bottom of the ladder to the bottom of the wall (along the ground, which is perpendicular to the wall) is 6 feet. When Benton places the base of the ladder 6 feet away from the wall and the top is resting at the top of the wall, it looks like a triangle, right?
Using pythagoras (this rule about right-angled triangles and stuff), we can already see that the two sides when simplified are 3:4. Because the 'triangle' is a right-angled triangle, the other side HAS to be 5 to complete the ratio. We just multiply it by 2 to get the correct ratio and that's your answer!
Its a line joining the points whose x and y coordinates add up to 3
Answer:
x = 4
Step-by-step explanation:
6^5x-4=6^4x
6^ (5x-4) = 6^ (4x)
Dividing through by 6
5x - 4 = 4x

5x - 4x = 4
x = 4
