Answer:
19
Step-by-step explanation:
9+10 is 19.
Answer:
x=2
Step-by-step explanation:
Solve for x:
-20 = -10 x
-20 = -10 x is equivalent to -10 x = -20:
-10 x = -20
Divide both sides of -10 x = -20 by -10:
(-10 x)/(-10) = (-20)/(-10)
(-10)/(-10) = 1:
x = (-20)/(-10)
The gcd of -20 and -10 is -10, so (-20)/(-10) = (-10×2)/(-10×1) = (-10)/(-10)×2 = 2:
Answer: x = 2
Answer:
Me too
Step-by-step explanation:
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:
