No parenthesis
So multiplication
2*3 =6 so
6/5+1/5 so fractions
They already have common denominators so just add the numerators and simplify
6+5 =11 so
11/5 = 2 1/5
The answer to your equation is
2 1/5
Method 1
You can use <span>The equilateral triangle </span>(look at the picture)
Method 2
You can use the <span>trigonometric function</span>

Answer:
One solution, x=-18/11.
Step-by-step explanation:
y=1/2x-7
y=6x+2
---------------
1/2x-7=6x+2
1/2x-7-6x=2
1/2x-6x=2+7
1/2x-12/2x=9
-11/2x=9
x=9/(-11/2)
x=(9/1)(-2/11)
x=-18/11
Hi! It will be a pleasure to help you finding the solution to this problem, so let's solve each part:
<h2>PART 1.</h2><h3>Finding the correct expression.</h3><h3>Correct answer:</h3>
From the problem, we know the following data of the problem:
- Laval parked at the beach.
- Laval paid a fixed price of $4 for a pass.
- Laval paid $1.50 for each hour.
Our goal is to find the the expression for the total cost for parking at the beach for h hours. So:
Step 1: Since we have a fixed price, this value will appear in our expression:
Step 2: Since Laval paid $1.50 for each hour, this can be represented as the following expression:
Finally, we can write total cost (C) as the sum of these two expressions:
Finally, our correct option is A:
<h2>PART 2.</h2><h3>Finding h.</h3><h3>Correct answer:</h3>
5 hours
Here we have to find how many hours Laval spent at the beach knowing that he paid a total amount of $11.50. From the previous part, we know that our expression is:
Finally, he spent 5 hours at the beach
Hi
(3x + 6)²
(3x + 6)(3x +6)
Distribute
(3x)(3x)+(3x)(6)+(6)(3x)+(6)(6)
9x² + 18x + 18x + 36
9x² + 36x + 36
A+ guaranteed!!!
