Hi there!
Let's solve this problem step by step!

To find f(3) we must substitute x = 3 into the formula.

Now we use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Work out the exponents inside the parenthesis first.

And finally multiply.

Hence, the answer is D. 64.

8x + 7 = 5
A "product" is the result of a multiplication operation. So the product of a number, ( which we will call x,) and 8 would be 8x. (Or 8*"x" number) 7 more than that product would be 8x + 7 = 5
Hope that this helps!
Answer:
Step-by-step explanation:
The distance between points A and C is 7 units, so to find the length we divide 35 by 7 which equals 5. Now we know that points B and D must be 5 units away from A and C, which means that B would be at (2, 3) and D would be at (2, -4). I hope this helps!
