Question

Mrs. Adenan sold 63 bracelets at one craft fair and 36 bracelets at a second craft fair. Which expression correctly applies the distributive property to show equivalent expressions for the total number of bracelets she sold? 63 + 36 = (3)(21) + (9)(4) 63 + 36 = (7)(9) + (12)(3) 63 + 36 = 9(7 + 4) 63 + 36 = 3(21 + 9)

Answer 1

C. The width of the flower box under the old scale is 12 ft.

Explanation:

length is 5 in, width is 3 in

scale drawing was 1 in to 4 ft

so the old length was : 5 * 4 = 20 ft

and the old width was : 3 * 4 = 12 ft <===

she changed the scale drawing from 1 in to 6 ft

so the new length is : 5 * 6 = 30 ft

and the new width is : 3 * 6 = 18 ft

Hope this Helps!

Answer 2

63 + 36...there is a common factor of 9
9(7 + 4) <== this is equivalent

63 + 36...there is a common factor of 3
3(21 + 12)...but this is not an answer choice...but it is equivalent
