Nathan and steven stacked boxes on a shelf. nathan lifted 13 boxes and steven lifted 15 boxes. the boxes that nathan lifted each weighed 12 lb more than the boxes steven lifted. let s represent the weight of the boxes that steven lifted. which expression represents the total number of pounds nathan lifted?
a. 12(s+13)
b. 13(s+12)
c. s + 12
d. 15(s+12)

13(s+12) pounds

B is correct.

Step-by-step explanation:

Nathan and Steven stacked boxes on a shelf.

Let s represent the weight of the boxes that Steven lifted.

The boxes that Nathan lifted each weighed 12 lb more than the boxes Steven lifted.

Weight of each box lifted by Nathan = (s+12) lb

Total number of box lifted by Nathan = 13

Total weight of boxes = Total number of box × Weight of each box  

                                    = 13 × (s+12)

Expression: 13(s+12) lb

Hence, The total weight of boxes lifted by Nathan will be 13(s+12) pounds

a - base

b - exponent

so,

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
