Since there are 3 lines (triangle), perimeter is simply the sum of those sides
find each side using distance (d) formula:
where two points of the line lie at (x1, y1) and (x2, y2)
let's name the points of our triangle to make it easier: A = (8, 2), B = (8, 6), C = (6, 6)
So now for P add AB + BC + AC = 4+2+4.47
P = 10.47 units squared

Answer:
Cost of Television = $294
Step-by-step explanation:
7% discount means 7/100 = 0.07 LESS
So we need to multiply by 1 - 0.07 = 0.93
Also, 10% MORE, or extra, means 10/100 = 0.10 MORE
So we need to multiply by 1 + 0.10 = 1.1
Let cost of television be "c", so we can say:
- 7% discount would mean cost to be c(0.93) = 0.93c
- 10% with interest would mean cost to be c(1.10) = 1.10c
The difference is 49.98. So we subtract lower value (0.93c) from larger value (1.10c) and equate to 49.98 and solve for c:
Cost of Television = $294
Answer:
8.57x+1.06
Step-by-step explanation:
add: 5.47x+3.1x = 8.57
add: -8.84+9.9 = 1.06
