Answer:

<h2>4 cuts.</h2>

Step-by-step explanation:

When we have a circle, each cut (supposing the curst are in the exact middle) which give use two haves. So, if we cut one time, we'll have two equal parts, if we cut a second time, we'll have 4 equal parts, a third time, we'll get us 6 equal parts, and if we cut a fourth time, we'll have 8 equal parts.

So, whenever we have this kind of problem dividing circles, we just say that each cut in the exact middle equals two equal haves, so if we have 4 cuts, we just multiply them by 2, 4(2)=8. Therefore, we have 8 equal parts.

Blizzard [7]

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.

How do you solve the first one
Dominik [7]

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
