I got 18. i did this by using the SOH CAH TOA method. In this case you have the the angle and the hypotenuse, and you’re looking for the adjacent side, therefore you need to use CAH
The distributive law states that a(b - c) = ab - ac
In this example a = 5/8, b = 7/9 and c = 11/6
Given:
Consider the sides of the triangle are 4x+10, 2x-5 and 18 (in feet).
Perimeter of this triangle is to be no more than 77 feet.
To find:
The inequality and solution of the inequality.
Solution:
Perimeter of a triangle is the sum of all side.
Perimeter of given triangle
Perimeter of this triangle is to be no more than 77 feet. It means perimeter must be less than or equal to 77.
Divide both sides by 6.
Therefore, the required inequality is and the solution is .
Your expression would be
because of the order of operations this expression is valid to the world problem
3.5x>7
x<2
8x<48
x>6
these all i know
