Answer:
Step-by-step explanation:
Sin(t)
Type in Sin in your calculator
Then the ‘t’ stands for the angle
So....
Sin(90)
Answer:
18, 19(which has two) 20(has two)
Step-by-step explanation:
Just find the ones that appear more than one time.
<span>The ratio of areas is the square of the ratio of perimeters;
The area of triangle B / The area of triangle A = 25 ;
The perimeter of triangle B / The perimeter of triangle A = </span>

The perimeter of triangle B is 5many times greater than the perimeter of<span>triangle A!</span>
I showed my steps, and 3y-4 does equal 5
Answer:
Hence, the system of equation does not have solution.
Step-by-step explanation:
You have the following 2x2 system:

You can obtain the solution to the system by using substitution method.
You solve the first equation for x:
(3)
Next, you replace (3) in the equation (2), and you solve for y:

The last result is the trivial solution. This means that the equation (2) is a multiple scale of the first equation. In fact, if you multiply equation (1) by -4, you obtain the equation (2).
Hence, the system of equations does not have solution.
