The triangles are similar. Set the two triangle's measurements equal to each other
8/10 = (x - 1)/(x + 2)
Cross multiply
8(x+ 2) = 10(x - 1)
Distribute the numbers
8(x) = 8x
8(2) = 16
10(x) = 10x
10(-1) = -10
8x + 16 = 10x - 10
Isolate the x. Subtract 16 from both sides, and 10x from both sides
8x (-10x) + 16 (-16) = 10x (-10x) - 10 (-16)
8x - 10x = -10 - 16
Simplify. Combine like terms
-2x = -26
Isolate the x. Divide -2 from both sides
-2x/-2 = -26/-2
x = -26/-2
x = 13
13 is your answer for x
hope this helps
Answer:
The limit does not exist
Step-by-step explanation
For this question you have to look at the function and see what y value does it approach as it gets closer and closer to x =2, from the left side it looks like it approaces 4 and from the left side it looks like it's approaching 1, since the limits from the left and right sides are not the same, the limit does not exist
The last one should be the answer
Answer:
Go with the 2nd choice.
Step-by-step explanation:
When using proportions to solve for unknown quantities, you need to keep the same units on the same side. This means keep "ft" on the top side and "mi" on the bottom side.
