Answer:
Irrational Numbers. An Irrational Number is a real number that cannot be written as a simple fraction. Irrational means not Rational. rational vs irrational.
Step-by-step explanation:
The first one is quadratic function
Answer:
C
Step-by-step explanation:
Area is W×L. The area of the rectangle is 6x^(2) + 7x - 3.
So we write that as 6x^(2) + 7x - 3 = W×L
We can factor 6x^(2) + 7x - 3 to see the width and length.
Then, you get (2x + 3) (3x - 1) = W × L
Now you have to values for width and length
The formula for perimeter is 2W + 2L, you can choose which is width and which is length
Next, substitute the values in the formula: 2(2x + 3) + 2(3x - 1) and solve it. Done! :)
Answer:
95 degrees
Step-by-step explanation:
First find the angles within the triangle. 180 - 43 - 52 = 85, so the missing angle within the triangle is 85. The exterior angle would be supplementary to that, so 180 - 85 = 95.
