Which equation has the solution x=4?

option c is the right answer

Step-by-step explanation:

x+8=3x                                                                                                                             or,8=3x-x                                                                                                                                                                                                                                                 or,8=2x                                                                                                                                                                            Therefore,x=4

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
