Find x

Help me please

x=31.2

Step-by-step explanation:

Since angle C is 4x-10 and angle A is 2x+3

then the two angles combined should equal 180 (based off of the inscribed quadrilateral theorem)

4x-10+2x+3=180

6x-7=180

6x=187

x=31.166...

if you round it to the nearest tenth it would be 31.2

1) 2x * 2x = 4x^2

2) 2(-1)+6 = 4

3) (4x)(6x+6) = 24x^2 + 4x

4) ((6)+4)(5(6)) = 300

5) 4x(x+1)= 4x^2+4x

6) (-x-3)(-5x+10) = 5x^2+5x-30

7) (2(4)+3)(5(4)-2) = 198

8) ((5)^2+2)(2(5)-1)=243
