bro i'm not too sure we can help you with this..
Answer:
x = 1/3
There is one solution
Step-by-step explanation:
3x -1= 1-3x
Add 3x to each side
3x+3x -1= 1-3x+3x
6x-1 =1
Add 1 to each ide
6x-1+1 = 1+1
6x =2
Divide each side by 6
6x/6 = 2/6
x = 1/3
There is one solution
Area of triangle = 1/2 (8)(4) = 16
Area of semi-circle = 1/2 (3.14)(4^2) = 1/2(3.14)(16) = 25.12
Area of figure = 16 + 25.12 = 41.12
answer
41.12 square units
Answer:
Step-by-step explanation:
Part A:
3x^2 -2x -1 + 9x + 2x^2-3 = 5x^2 + 7x -4
Part B
5x^3 + 4x^2 -x-3 -(5x^2 +7x-4) = 5x^3 -x^2-8x+1
Part C:
They do show polynomials are closed for addition and subtraction because both resulted in another polynomial
