Answer:
equation: 10 + 0.05x=22
Step-by-step explanation:
the next step after writing the equation would be to subtract 10 from both sides to get 0.05x=12. after this you would then have to divide 12 by 0.05 to get 240 minutes. you could check it by putting 240 in for x to get 10+0.05(240)=22. you would then multiply 0.05 by 240 to get 12 and then add 10 onto it to get 22 which was already given.

Answer:
no
Step-by-step explanation:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
9+10 > 21
19 >21
This is not true so it cannot make a triangle
Answer:
x= -2 x=-2
Step-by-step explanation:
move over the leading coefficient and you get
3x²+12x+12
the pull out a 3 because that's your gcf and 3 cannot equal zero so you can just do without id and you get
x²+4x+4
and when you factor that you get
(x+2)(x+2)
and when you set those equal to zero you get x= -2 and x= -2
