Hey there,
9c + 4 = - 23
9c = -23 - 4
9c = -27
c = -27 / 9
   = - 3
Whenever a number crosses an equal sign, it become its opposite. For example- when 4 crosses an equal sign it becomes - 4

Hope this helps :))

Point A is at -5 and point B is at 11.<br> What is the distance of AB?
Allisa [31]

Answer:

The distance of AB would be 16.

Step-by-step explanation:

There are several ways to do this. But the way that would probably be easier for u to understand would be if you found the distance of -5 from 0. Remember targ distance is always positive so the distance would be 5 points. Then u have to get to point B or also 11. That means you have to move 11 points Altogether if you add 5 and 11 you get 16.

Verify sin (360-theta)=-sin theta
Lesechka [4]

Answer:

That is truth

Step-by-step explanation:

Remember that sin(x-y)= sin(x)*cos(y) + sin(y)*cos(x)

Lets evaluate x=360, y=theta

sin(360-theta)=sin(360)*cos(theta) -sin(theta)*cos(360)

Also, remember that sin(360)=sin(0)=0

Cos(360)=cos(0)=1

Thus

Sin(360-theta)=-sin(theta)

Effectus [21]

Answer:

solution:-

diameter of a cylinder (d) = 12 cm

length(h) = 30 cm

curved surface area of cylinder (csa) = ?

we know that ,

therefore , csa of cylinder = 2πrh

r = d/2

or, r = 12/2= 6 cm

Then, csa if cylinder = 2 ×22/7×30

= 2×22×30/7

= 1320/7

= 188.57 Square cm Ans,......
