Anyone me it is a very simple question: sarah buys 6 cups and 6 mugs. a cup cost £x a mug costs £(x+3) a) write down an expression, in terms of x, for the total cost, in pounds, of 6 cups and 6 mugs.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
