e you..........
1.)Which expression is equivalent to −4.6+(−0.4)+(−7.2) ?

(4.6+0.4)+(−7.2)
(4.6+0.4+7.2)
−4.6−(0.4+7.2)
−(4.6−0.4)+(−7.2)

2.)Which expression is equivalent to −40+(−20)+(−60) ?

−40−(20−60)
−(40−20)+(−60)
−20+(−40)+(−60)
40+20+60

3.) correctly identify the property shown here

Answer:

<u><em>canvases over weeks </em></u>

<u><em> </em></u>

<u><em>Step-by-step explanation: </em></u>

<u><em> </em></u>

<u><em>Given: </em></u>

<u><em> </em></u>

<u><em>w(h) represents how many hours per week </em></u>

<u><em> </em></u>

<u><em>c(t) approximates how many canvases she paints per hour </em></u>

<u><em> </em></u>

<u><em>In function composition, if we have two function f(x) and g(x) then </em></u>

<u><em> </em></u>

<u><em>(f.g)(x) or f(g(x)) means first apply g(), then apply f() i.e. applying function f to the results of function g. </em></u>

<u><em> </em></u>

<u><em>Now we have c(w(h)), this means first we apply w(h) which will give us hours per week and then we'll apply function 'c' on the results of 'w' (that is number of hours for weeks painted). As result we'll get number of canvas </em></u>per week!
