Given
and 
Required
The scale factor from

Take a corresponding side in both triangles.
We have:

The scale factor from
to
is:



Answer:
70
Step-by-step explanation:
A=a+b
2h=8+12
2·7=70
Bear in mind the Unit Circle is called so, because its radius is exactly 1, thus just 1 unit, the Unit Circle
anyway
Answer:
Either B or D.
Step-by-step explanation:
I consider both options valid. It all depends on how the employer is keeping track of time, ie if the pay "ticks" every 60 minutes, or an employee is allowed to clock in half hours.
Will I be able to work 30 and a half hour for example? If I'm allowed to, D.
If I have to work multiple of 60 minutes, B.
Group and factor
undistribute then undistribute again
remember
ab+ac=a(b+c)
this is important
6d^4+4d^3-6d^2-4d
undistribute 2d
2d(3d^3+2d^2-3d-2)
group insides
2d[(3d^3+2d^2)+(-3d-2)]
undistribute
2d[(d^2)(3d+2)+(-1)(3d+2)]
undistribute the (3d+2) part
(2d)(d^2-1)(3d+2)
factor that difference of 2 perfect squares
(2d)(d-1)(d+1)(3d+2)
77.
group
(45z^3+20z^2)+(9z+4)
factor
(5z^2)(9z+4)+(1)(9z+4)
undistribuet (9z+4)
(5z^2+1)(9z+4)
