X= 20 degrees. Your welcome if it were a little less sloppy it would probably make much more sense.
Answer:
x=-7 x=2
Step-by-step explanation:
x^2+5x-14=0
Factor
What 2 numbers multiply to -14 and add to 5
7*-2 = 14
7 -2 =5
(x+7) (x-2) = 0
Using the zero product property
x+7 = 0 x-2 =0
x=-7 x=2
Answer:
210 km
Step-by-step explanation:
90 * 2 is 180 (distance over 2 hours)
20 minutes is .333 hours, so 90*0.333 is about 30 km
and 180+30 is 210.
Answer:
a1=3, a2=6, a3=12, a4=24, a5=48
Step-by-step explanation:
a7=a*r^6=192
a10=a*r^9=1536, r^3=8, r=2 and a=3
a1=3, a2=6, a3=12, a4=24, a5=48
Do you mean checking your work? In that case it would be 9*20.
