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

DaniilM [7]
Let
x = the number of shorts bought
y =  the number of t-shirts bought

A pair of shorts costs $16 and a t-shirt costs $10. Brandom has $100 to spend.
Therefore
16x + 10y ≤ 100
This may be written as
y ≤ - 1.6x + 10                 (1)

Brandon wants at least 2 pairs of shorts. Therefore
x ≥ 2                               (2)

Graph the equations y = -1.6x + 10 and  x = 2.
The shaded region satisfies both inequalities.

Answer:
Two possible solutions are
(a) 3 pairs of shorts and 4 t-shirts,
(b) 4 pairs of shorts and 2 t-shirts.
