Hello:
3x²+5x+2=0
delta = (5)²-4(3)(2)=1
x =( -5 <span>±1)/6
x= -2/3 or x=-1
t4-81=(t²)² -9² = (t²-9)(t²+9) =(t-3)(t+3)(t²+9)....(answer B)</span>
The answer would be b that is bc you answer is decreasing. As you x increase.
Answer:
y=88 and x=23 because 4x=3x+23 and y+4x=180
SAME: Both measure a circle
DIFFERENT: Circumference measures AROUND the circle and the area measures the entire circle.
Answer:
1.
p=M/V. by rearranging this formula you get
V=M/p
V=560kg/7kg/m³
=80m³ b/c kg canceled kg
2.
p=M/V
=352kg/220m³
=1.6kg/m³
