Step-by-step explanation:
The degree of a polynomial is determined by the value of the largest exponent of the variable.
Given
4x + 2x³
The largest exponent is 3, thus the polynomial is of degree 3
A polynomial of degree 3 is called a cubic
Answer:
A: X=1
Step-by-step explanation:
If DE=2, and E to C is of the same line but is less than half of DE, it has to be the smallest number possible. 6(1)-8=-2
Answer:
32
Step-by-step explanation:
The perimeter of a figure is the sum of all the sides.
So, add up all the sides which equals the perimeter.
And we are given that the perimeter is 66. Thus:
Combine like terms:
Add 4 to both sides:
Divide both sides by 10:
So, z is 7.
And VW is 5z-3. Thus:
Our answer is 32 :)
