Answer:
The simplified version of that equation would be 
.
Step-by-step explanation:
Since 
and 
have the same exponent and variable, we can combine them normally.
- =
Answer:
2
Step-by-step explanation:
(8-x)(8+x)
8×8=64
-x·+x=-x^2
64-x^2
I got B but I'll show you how I got that answer.
Let's look at AB and BC. AB = 3 and BC = 4.
3/4 = 0.75
On the triangle, AB = 90. And BC = 10x - 20. We need to solve for x and prove that AB/BC = 0.75.
Let's start with Choice A.
10(11) - 20 = 90.
AB = 90
BC = 90.
90/90 = 1. It doesn't equal 0.75. Meaning this answer is wrong.
Now let's look at Choice B.
10(14) - 20 = 120.
AB = 90
BC = 120
90/120 = 0.75
So, 3:4 = 90:120 making Choice B the correct Answer. Let me know if this is correct
Answer:
his tip will be $3.21
Step-by-step explanation:
17.85 times 0.18
multiply and get 3.213
round that to $3.21
22. P(n > 3) = P(4)+P(5) = (4+5)/30 = 9/30 = 3/10
23. The game isn't fair because there as many even numbers as there are odd numbers on a die. You get double the points he gets at the same chance!
