GUYS WHATS 1+1 ?!?!?!?! I CANT FIGURE IT OUT

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no

Solve the following: 12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1) 364x–64x=300x
