Answer:
14 days
Step-by-step explanation:
5x2=10
140÷10=14
Step-by-step explanation:
From Pythagorean theorem, one of the sides can be determined as x^2 + y^2 =8^2
or y = (8^2 - x^2)^(1/2)
we can write the perimeter P as
P = 2x + 2y ---> 20 = 2x + 2(8^2 - x^2)^(1/2)
Dividing by 2, we get
10 = x + (8^2 - x^2)^(1/2)
Move the x to the other side,
10 - x = (8^2 - x^2)^(1/2)
Take the square of both sides to get rid of the radical sign:
(10 - x)^2 = 8^2 - x^2
Move everything to the left and expand the quantity inside the parenthesis:
x^2 + (100 - 20x + x^2) - 64 = 0
2x^2 - 20x + 64 = 0
or
x^2 - 10x + 32 = 0
Now we can see that a = -10 and b = 32
Is it cheaper then without it? If so you should
Answer: 83,662,774
Step-by-step explanation:
The area of this figure is 532m.
First you do the square which is 18 time 18 gets you 324m.
The for the first triangle you would do 18 times 16 then divide by 2 which is 144m.
For the last triangle you would do 16•8 div by 2 which will give you 64m.
Add them all up and you get 532m.
