hope this helps

have a good dya :)

Step-by-step explanation:

5535

Step-by-step explanation:

When multiplying multi-digit numbers, you can break it down to more multiplication problems. The number of digits in the second number are how many problems you can make. In this case it is 2.

123 × 5

123 × 40

A.3 and -2

Step-by-step explanation:

The cost of one pen is undefined when..;

(2x^2 - x - 10)/(x^2 - x - 6) = 1/0then interchange..by putting the denominator as the numerator and numerator as the denominator on both sides of the equation,which then would give us...;

(x^2 - x - 6)/(2x^2 - x - 10) = 0/1

Which then if simplified it would give us..;

;(x^2 - x - 6) = 0in which we simpilify the quadratic expression,

;(x - 3)(x + 2) = 0

Hence the choices of x...are then solved by;

(x - 3) = 0our first choice...x = 3,

(x + 2) = 0our second choice...x = -2
