Step-by-step explanation:
(a^2+3b)/(c-2d)
substitute a=3,b=8,c=2,d=5
(3^2+3(8))/(2-2(5))
=(9+24)/(2-10)
=33/(-8)
=-4.125
Answer:
22
Step-by-step explanation:
f(x)=(3x+4)-(2-x)
Let x =5
f(5)=(3*5+4)-(2-5)
Do the parentheses first
= (15+4) - (2-5)
= 19-(-3)
= 19+3
= 22
The correct answer is A i believe :)
<span>There are several ways to find the max of min of a quadratic equation.
Max occurs when t = -b/2a
t = -b/2a = -68/(2*-4.9) = 6.93 second
Max altitude = h(6.93) = 68(6.93)-4.9(6.93^2) = 235.92 meters

So in comments section, the legnth is 6 feet width is 5 feet height is 3.5 feet and pool is rectangular prism
volume=legnth times width times height
volume=45
legnth=6
width=5
find height
subsitute
45=6 times 5 height
45=30 time height
divide both sides by 30
1.5=height
answe ris pool is 1.5 feet tall
