Hello,
I)
1 solution with multiplicity 2
(2x+1)²=0
II) ANSWER C (-4.41, -1.59)
-3-√2 and -3+√2
III)
y=x²+2x
y=3x+20
==>x²+2x=3x+20
==>x²-x-20=
Δ=1+4*20=81=9²
(x=(1-9)/2=-4 and y= 3*(-4)+20=8 ) or (x=(1+9)/2=5 and y=3*5+20=35)
Answer:
Step-by-step explanation:
The average length of the weird trapezoidal shape on the left is
(2 m + 10 m)/2, or 6 m. The width is 4 m, so the area is 24 m^2.
The area of the semicircle is (1/2)(pi)(2 m)^2, or 2pi m^2.
Thus, the overall area of the green shape is 24 m^2 + 2pi m^2.
