Answer:

256 ft²

Step-by-step explanation:

SA=2(lw+lh+wh) where l is length and w is width and h is height

Plug in the given information

SA=2(5*4+5*12+4*12)\\SA=2(20+60+48)\\SA=2(80+48)\\SA=2(128)\\SA=2(128)\\SA=256

Therefore, the surface area of the rectangular prism is 256 ft².

I hope this helps!

Answer:

<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>

We know that

SA = 2(lw + wh + lh)

SA = 2[(5 × 4) + (4 × 12) + (5 × 12)]

SA = 2[20 + 48 + 60]

SA = 2[128]

SA = 256 ft²

Sholpan [36]

<u>Answer:</u>

An equation that relates the speeds of the two legs of the trip

  \frac{640}{x-40}+\frac{640}{x}=4

<u>Explanation:</u>

Given, we have to use x to represent the speed on the second leg

Speed on first leg when increasing your speed by 40 mph will be (x-40)

Distance is given as 640 miles and time is calculated as  

\text { Time }=\frac{\text { Distance travelled }}{\text { speed }}

According to the question, increasing speed saved four hours

Therefore, the equation that relates the speeds of the two legs of the trip will be

\frac{640}{x-40}+\frac{640}{x}=4
