Simplify -4-3×5+(-7+5)​

simplify -4-3×5+(-7+5)

BODMAS Rule i.e. order of solving a polynomial :-

-4 -3 × 5 + ( -7 + 5 )

Solving the brackets first of all, We get,

⇒ -4 -3 × 5 -2

Now multiplying -3 and 5, We get,

⇒ -4 -15 -2

⇒ -21

∴ Simplifying -4-3×5+(-7+5), We get, -21

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.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
