Answer:
Step-by-step explanation:
50% is but we're working with 64 units, not 100. So, we must find a number that represents 50 but in 64 units.
If you solve for x, you get:

(4, 2) and (8, 1) (option D)
Explanation:
The given equation:
y = 4x - 1
comparing with equation of line:
y = mx + c
m = slope = 4
c = y-intercept = -1
For a line to be perpendicular to another line, the slope of one line will be the negative reciprocal of the other line.
We need to find the option which will give a negative reciprocal of 4.
a) (1, -3) and (2, 1)
b) (-4, 7) and (-1, -5)
c) (-8, -4) and (0, -2)
d) (4, 2) and (8, 1)
slope = 4
reciprocal of 4 = 1/4
negative reciprocal = - 1/4
Hence, the option whose slope gives the negative reciprocal of 4 is (4, 2) and (8, 1) (option D)
for perimeter you need to add, 15ft, 80ft, 30ft, 50ft, and 60ft which is 235 feet
for area you need to multiply 15ft times 80ft to get the area of the long verticle one which is 1200
then multiply 50ft times 30ft which is 1500
then add 1200 and 1500 which is 2700ft^2
