Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o

I hope that this helps you!
This is rather a sneaky question. You don't know exactly what numbers you can use and what numbers not.
For example, are you allowed to use x = - 3. The answer is yes
f(-3) = 2*7^(-3) = 2/7^3 = 2/147.
How about 0? If there is going to be a problem, zero is usually the number that causes the problem.
f(0) = 2*7^(0) = 2 * 1 = 2 and in this case 0 is just fine.
How about positive numbers? No they are all good.
So the range is -∞ < y < ∞

Answer:
22
Step-by-step explanation:
4x4+8-2
Using PEMDAS, assuming theres no parentheses.
First do 4x4 which is 16.
16+8-2
You are left with 22.
