This should be the correct answer 3x2(2x2+4)
75 problems
3/5 of an hours is 36 minutes you can then do 45 over 36 mins and set it equal to x over 60 mins then you do 45 times 60 which equals 2700 then you divide 2700 by 36 and you get 75
A=pi *r^2=pi *(D/2)^2=3,14*D^2/4
⇒D^2=4*A/3,14=4*50/3,14=200/3,14≈63,7
D≈V63,7
6-x=5x+30
+x. +x
6=6x+30
-30. -30
-24=6x
X=-4
The answer is -4
Answer:
C
Step-by-step explanation:
the quadratic formula is

Make the quadratic equal to 0, so it will be 3x^2 + 8x -2=0. Then substitute the values into the equation.
