10 × tan18° × 2 = 20 × tan18°

The area is: ½ × 20 × tan18° × 10 × 10 = 1000 × tan18°

≈ 324.9

7x - 4 = -4 Solve for x. Please show your work. Thanks!
Bingel [31]
X=0 is definitely the answer but I belive how u solve it is 7×X=0 and that leaves -4 because it would be 0-4 so u just take out the zero. I think, but the answer is 0.
