<h3>
Answer: A) 52 square inches</h3>
==========================================================
Explanation:
a = 8, b = 13, and c = 15 are the sides of the triangle
s = (a+b+c)/2 = (8+13+15)/2 = 18 is the semi-perimeter, aka half the perimeter.
Those values are then plugged into Heron's Formula below
The triangular plaque has an area of approximately 52 square inches.
Answer:
3x + 2y = 16
x = 2 , y = 5
Step-by-step explanation:
Given that George bought x quarts at $3.00 per quart & y quarts at $2.00 per quart and he bought 7 quarts for $16.00
Considering the total cost
3x + 2y = 16
For the cost of each
x + y = 7
solving the 2 equations simultaneously be substitution
x = 7 - y
3(7 - y) + 2y = 16
21 - 3y + 2y = 16
-3y + 2y = 16 - 21
-y = - 5
Divide both sides by -1
y = 5
x = 7 -y
x = 7 - 5
= 2

Answer:
4a. S = 300c
4b. S = 2400
Step-by-step explanation:
4a. There are 300 seats in a conference room 'c' so to find the amount of seats there are in total you need to times these values so...
S = 300c
4b. substituting 8 into c gets
S = 300x8
S = 2400
hope this helps!
