An auto mechanic ordered eight car spark plugs and four truck spark plugs. car spark plugs cost $.75, and truck spark plugs cost $3.00 apiece. use the distributive property to find the total cost of these parts.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
