Answer:
14
Step-by-step explanation:
So we have the expression:
Substitute 2 for a, 3 for b, and 4 for c:
Multiply:
Add:
We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.
Side PQ =
Side QR =
Side RP =
So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7
You probably misplaced the digits in option A. The correct answer is 19.7 units.
Greetings! let’s solve this shall we?
So,
7x + 14 > -3x - 6
14 > -3x - 6 + 7x
14 > 4x - 6
20 > 4x
5 > x
Answer: -8.91, -2.8, 0.62, 4.56
Step-by-step explanation:
The negative numbers are smaller than the positive ones. The larger number behind the negative sign is smaller. Therefore, -8.91 is smaller than -2.8 so -8.91 is first and -2.8 is second. The last two numbers are positive so you compare them. 0.62 is smaller than 4.56 so the list of decimals from smallest to largest is -8.91, -2.8, 0.62, 4.56.
Hope this helps!
