Answer:

Box A is greater than Box B by 34.

Step-by-step explanation:

First, you need to start with finding the surface area of every individual side   on Box A we have side A, B, and C. After finding the individual area for each side,  double each area because there is two of each side. This is the the same method you apply to Box B.

Then subtract the surface area of Box B from Box A.

Andreas93 [3]

Answer:

2 hours

Step-by-step explanation:

First we need to know the distance Liam travelled using the bike.

If his speed was 8 mph and he travelled 3 hours, the distance travelled by bike is:

d = 8 * 3 = 24 miles

The total distance is 30 miles, so the remaining is:

30 - 24 = 6 miles

He travelled 6 miles with the speed of 3 mph, so the time walking is:

time = 6 / 3 = 2 hours

Which expressions are equivalent to the one below? Check all that apply. 21^x/3^x
satela [25.4K]

Answer:

<em>options:  A,C,E </em>are correct.

Step-by-step explanation:

We have to find the expression equivalent to the expression:

\dfrac{21^x}{3^x}

we know that: 21^x=(3\times7)^x\\\\21^x=3^x\times7^x

Hence,

\dfrac{21^x}{3^x}=\dfrac{3^x\times7^x}{3^x}=7^x-----(1)

A)   (\dfrac{21}{3})^x= 7^x  (same as(1))

Hence, option A is correct.

B)  7 ; which is a different expression from (1)

Option B is incorrect.

C) 7^x   (Same as (1))

Option C is correct.

D) (21-3)^x=18^x   which is a different expression from (1)

Hence, option D is incorrect.

E) \dfrac{7^x\times3^x}{3^x}=7^x   ; which is same as (1)

Hence, Option E is correct.

F) 3^x  ; which is not same as expression (1)

Hence, option F is incorrect.

baherus [9]

Answer:

Yes.

Step-by-step explanation:

In a direct proportional relationship, as one object gets larger, the other object gets larger as well. This fits that definition, as when the amount of video games bought increases, so does the amount of money spent.
