8 which equations can you use to find the value of Select all that apply. A X 120 + 85 = 180 B X + 85 120 C + 120 + 95 = 360 DX60 + 85 E X+60 + 85 = 180 F x + 35 = 180​

120 + 85 = 180 - Incorrect

B X + 85 120 - Incorrect

C + 120 + 95 = 360 so C = 145

DX60 + 85 = 145

E X+60 + 85 = 180 so E is 35

F x + 35 = 180​ so F is 145

Step-by-step explanation:

120 + 85 = 180

B X + 85 120

C + 120 + 95 = 360

DX60 + 85

E X+60 + 85 = 180

F x + 35 = 180​

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
