Answer:
-5y + 3x (or) 3x - 5y
Step-by-step explanation:
-8y-(x-4x)+3y
Solve the problem in the parentheses first. (x-4x)
-8y-(-3x)+3y
The problem within the parentheses is as simplified as we are going to get it. Now we can simplify the y values. (-8y + 3y)
-(-3x) -8y+3y
-(-3x) - 5y
Get our x value out of the parentheses now. -(-3x)
-(-3x) = +3x (two negatives makes a positive)
This leaves us with our simplified equation.
3x - 5y
or
-5y +3x
Pythagorean theorem = a^2 + b^2 = c^2
2^2 + b^2 = 4^2
4 + b^2 = 16
-4 -4
b^2 = 12
Square root
b = 3.5 rounded to the tenths place
The leg is 3.5 units
Hope this helps!
for number 5, you take the area of the area of the fountain, which is pi * radius squared. this is equivalent to 3.14 * 4^2. then to simplify I made it 3.14 times 16 and then got the answer of 50.24. Then you take the area of the fountain plus the path, which makes the diameter 9.5 divide that by 2 to get the radius, which is 4.75. pi * 4.75^2 is about 70.85. then you subtract the two(70.85-50.24) to get 20.61. since its 10 dollars per square meter, you multiply 20.61 by 10 to get 206.10 dollars. That is your answer.
