On a spring scale that measures force, a reading shows the force of an object to be about halfway between 7 n and 8 n. which of the following would be the most accurate measurement for the force? 0.0075 n 0.7 5 n 750 n 7.5 n

Only 7.5 would be correctly positioned between 7 and 8.

Suggestion: Next time, present your answer choices as

0.0075 N

0.75 N

750 N

7.5 N

It's difficult to determine what you meant by "N 7.5 N."

i have no clue at all sorry

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
