Answer:
Step-by-step explanation:
We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.
This can be represented as a triangle, where x is the unknown side.

4.5
We can use The Pythagorean Theorem to find the value of x. The theorem states that 
, where a and b are the lengths of the legs and c is the length of the hypotenuse.
However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.

Answer:
c) 31
Step-by-step explanation:
Given: f(x) = 3x + 1
We are being asked to find the function's value for x = 10.
Substitute 10 as the value of x in the function:
⇒ f(x) = 3x + 1
⇒ f(10) = 3(10) + 1
⇒ f(10) = 30 + 1
⇒ f(10) = 31
Therefore, the function's value at x = 10 is 31.

Step-by-step explanation:
1. multiply put the brackets
so it'll be 2d+6+3d-9
2. put into into like terms
2d+3d is 5d
6-9 is -3
There fore the answer is option B where it will be 5d-3
