I think the answer to this is a rate
Answer:
2257 pounds
Step-by-step explanation:
First, get the volume of each and since density is the same, we shall use the density to get the other mass
First volume
Volume=lwh where l is length, w is width and h is height.
Substituting with the given figures
Volume=4*9*168=6048
Density
Density is mass per unit volume
D=m/v
Mass is given as 7900 pounds
Density is 7900/6048=1.3062169312169
Volume of second box
V=2*6*144=1728
Mass is product of volume and density hence 1.3062169312169*1728=2257.1428571428 pounds
Rounded off as 2257 pounds
Answer:
(x-7)
Step-by-step explanation:
Recall that the area of a rectangle A whose length is l an d width is w
= l * w
Given that the area is
= x2 – 9x + 14
Factorize
x2 – 9x + 14 = x2 – 7x - 2x + 14
= x(x - 7) -2(x - 7)
= (x - 2)(x - 7)
Given that the width of yard is (x – 2) then the length will be (x-7)
