Find a vector v→ parallel to the intersection of the planes 2z−(x+4y)=4 and −(3x+3y+z)=7.

Triangles abc and dfg are given. find the lengths of all other sides of these triangles if: b ∠a≅∠d, ab·dg=ac·df, ac=7 cm, bc=15 cm, fg=20 cm, and df-ab=3 cm.

Urgentwhat is the area of the figure?

Rewrite the point-slope equation in slope-intercept form: y - 3 = 2(x + 4)
