Use distributive property to find (45×51
)

Answer&Step-by-step explanation:

Probably, you are being asked to do this to practice multiplying two sums together. At some point you might be multiplying binomials with variables like

(x+2)(x-7) If you already know how to do this, such as with a method like FOIL, or an area model like a box method, use that method.

So for this question use (40+5)(50+1)

See image. It takes four separate multiplications to find this product. Then add up all the parts. See image.

rounding to the nearest thousandth would be 452,000
