Answer:
x=±√−9
No real solutions.
Step-by-step explanation:
Step 1: Add 3x^2 to both sides.
27+3x2=−3x2+3x2
3x2+27=0
Step 2: Subtract 27 from both sides.
3x2+27−27=0−27
3x2=−27
Step 3: Divide both sides by 3.
3x2
/3
=
−27
/3
x2=−9
Step 4: Take square root.
x=±√−9
Whole numbers are positive numbers without decimals. First, list all the whole number factors of 36:
1 and 36
2 and 18
3 and 12
4 and 9
6 and 6
Next, see which one of those pairs has the highest sum:
1+36=37
2+18=20
3+12=15
4+9=13
6+6=12
The greatest possible sum the numbers can have is 37.
Hope this helps!!

Answer: The last one is equal to 72
Step-by-step explanation:
2^3*3^2
2*2*2*3*3=72
F(x) = (x-16)(x+16)
f(x) = (x - 16)²
To find the maximum, we set the first derivative equal to 0 and then calculate x.
f'(x) = 2(x - 16)
0 = 2(x - 16)
x = 16
The maximum height of the road is 16 feet.
