Hey there!
They are both correct, and their expressions are equivalent.'
9(S + T) + 45 = 9S + 9T + 45
Have a terrificly amazing day!
Answer:
502 m²
Step-by-step explanation:
We require to find b before calculating the surface area.
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here V = 510, l = b, b = 10 and h = 3, thus
b × 10 × 3 = 510
30b = 510 ( divide both sides by 30 )
b = 17
--------------------------
The opposite faces of a cuboid are congruent, thus
top/bottom area = 2(17 × 10) = 2 × 170 = 340 m²
front/back area = 2(17 × 3) = 2 × 51 = 102 m²
sides area = 2(10 × 3) = 2 × 30 = 60 m²
Surface area = 340 + 102 + 60 = 502 m²

Answer:
Step-by-step explanation:
The units that we should use are gallons per day, we get:
<h3>
Which units should we use?</h3>
We want to express the fact that every day you use 2.4 gallons of gasoline.
So we have two types of units in the above sentence, time (in days), and volume (of the gasoline consumed).
Then we conclude that the units that we should use is volume over time, particularly, gallons per day.
So we can represent that measure as:
