Answer:
You have a chance of getting any of those.
Step-by-step explanation:
If you were to flip the first coin, and it would be either heads or tails 50% chance.
If you flipped the second coin, without cancelling the first, it would be 25% chance
If you flipped the third coin, without cancelling the first it would be 12.5% chance
(this is all for heads)
Factoring - I always found this to be easy (one of the few things in math that I felt was easy!)
x^2 + 20x + 100 = 36
First step is to get the right side to zero. Do this by subtracting 36.
x^2 + 20x + 64 = 0
Now we have to factor the expression. We could use quadratic formula, completing the square, or use the product/sum rule if possible (which it is).
64's factors are:
1, 64
2, 32
4, 16
8, 8
We need the two factors that sum to 20...
(x + 4)(x + 16) = 0
Set each factor to zero
x + 4 = 0 and x + 16 = 0
Solve each equation
x = -4 and x = -16
You should always check for extraneous solutions. I recommend using desmos.com to check answers!
The simplified expression of 4/x is at most 3 is 3x ≥ 4
<h3>How to graph the expression?</h3>
The statement is given as:
4/x is at most 3
Express as inequality: (at most means ≤)
So, we have:
4/x ≤ 3
Multiply both sides by x
4 ≤ 3x
Rewrite as:
3x ≥ 4
See attachment for the graph of the inequality

Answer:
45
Step-by-step explanation:
Given the legs of the right triangle.
Then using Pythagoras' identity
The square oh the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is
h² = 36² + 27² = 1296 + 729 = 2025 ( take the square root of both sides )
h =
= 45
