Would love some help on these :)

1) Solve : ( 2 * + 1 ) ( x - 2 ) = - 3 (2) A sign is to have the shape of a triangle with a height oft greater than the length of the base. How long should the base be if the area is to be 1 4 f+2 ( Please use equation to solve). The cost of a pizza varies directly as the square of its radius . If a pizza with a F-inch radius cost $6, how much should a pizza with a ginch radius cost? ( Please use formulas and equations to solve). Simplify : 4 x + 3 3 4 2 x+1/x+30 X+ 6 *+ 5 5 Solve : 4 x + 3 3 = 2 x + 1/ x + 30 x + 6 X + 5 6 Use SIMILAR TRIANGLES to find the Length of the unknown sides : X+2 5 14 X - 1
