The answer choice is a. y=(-1/2)x
Square root (x + 8) -6 = x
square root (x + 8) = x -6
x^2 + 16x + 64 = x^2 -12x + 36
28x = 48

Answer:
Length 100 m, width 85 m.
Step-by-step explanation:
If the perimeters are equal then the sum width + length has to be the same as 70 + 115 = 185.
The area of the given field = 115 * 70 = 8050 m^2.
Lets try length 100 and width 85 .This gives an area of 8500 so that would fit.

Answer:
62.5 oz of 100%
Step-by-step explanation:
Let p represent the number of ounces of pure syrup. Then (100-p) is the number of ounces of 60% syrup. The amount of maple syrup in the desired mix is ...
p +0.60(100 -p) = 0.85(100)
0.40p +60 = 85 . . . . . . . . . . . simplify
0.40p = 25 . . . . . . . . . . subtract 60
p = 62.5 . . . . . . . . . divide by 0.4
62.5 ounces of pure syrup should be mixed with the diluted syrup to make 100 ounces of 85% maple syrup.
_____
The other 37.5 ounces will be 60% syrup.
