Answer:
The length of this rectangle is 6 units.
Step-by-step explanation:
Let the width of the rectangle be x.
x • (x+2) = 48
x^2+2x=48
x^2+2x-48=0
x^2 - 6x + 8x - 48
x(x-6) 8(x-6)
(x+8)(x-6)
x=-8,6
A = b is given to us
Multiply both sides by c to get
a = b
a*c = b*c
The rule to multiply both sides by c is the multiplicative property of equality
Then on the right side, replace c with d. This replacement is possible due to the fact that c = d. This is using the substitution property.
So we go from
a*c = b*c
to this
a*c = b*d
Answer:
B.
Step-by-step explanation:
If you simple this expression we can see that 7/35 will simplify to 1/5 first. As for the exponents, you can write them out to make it easier to cancel, shown in the photo.
Answer:
Mean volume shipped per trailer load = 2960 ft³
Step-by-step explanation:
Since both trailers are always full,
Total volume in one 30 feet trailer shipment = 8 × 10 × 30 = 2400 ft³
Total volume in one 40 feet trailer shipment = 8 × 10 × 40 = 3200 ft³
Assuming a basis of 10 shipments, 3 shipments are done using the 2400 ft³ trailer and 7 shipments are done using the 3200 ft³ trailer.
Mean volume shipped per trailer load = total volume shipped/number of shipments
Total volume shipped = (3 × 2400) + (7 × 3200) = 7200 + 22400 = 29600 ft³
Number of shipment in the basis used = 10
Mean volume shipped per trailer load = 29600/10 = 2960 ft³
