Answer:

57 cm²

Step-by-step explanation:

Surface area of the yellow prism = front + back + right + left + top

✔️Area of the front = L * W

L = 4 cm

W = 3 cm

Area of the front = 4*3 = 12 cm²

✔️Area of the back = L * W

L = 4 cm

W = 3 cm

Area of the back = 4*3 = 12 cm²

✔️Area of the right face = L * W

L = 4 cm

W = 3 cm

Area of the right face = 4*3 = 12 cm²

✔️Area of the left face = L * W

L = 4 cm

W = 3 cm

Area of the left face = 4*3 = 12 cm²

✔️Area of the top = L * W

L = 3 cm

W = 3 cm

Area of the top = 3*3 = 9 cm²

✅Total = 12 + 12 + 12 + 12 + 9 = 57 cm²

What is y=x-4 2x+y=5
ahrayia [7]
If you would like to solve y = x - 4 and 2 * x + y = 5, you can do this using the following steps:

y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9     /3
x = 9 / 3 
x = 3

y = x - 4 = 3 - 4 = -1

The correct result would be x = 3 and y = -1.

Rachel has 20 nickels, dimes, and quarters worth $3.70. if she has twice as many quarters as dimes, how many nickels does she ha
marta [7]

Answer: 2 nickels

Rachel has 20 coins composed of nickles, dimes and quarters amounting to $3.70. Her quarters are twice the number of her dimes, the number of nickels can be computed as follows:

If  X= the number of dimes  at .10 each

Then  2x= the number of quarters at .25 each and

20-(X-2X)= the number of nickels at .05 each

<span> <span><span> <span> The equation will be: X(.1)+2(X).25+(20-X-2X).10=3.70 </span> </span> <span> </span> <span> <span> .1X+2X(.25)+(20-X-2X).05=3.70 </span> </span> <span> <span> .1X+.5X+(20-3X).05=3.70 </span> </span> <span> <span> .6X+(1-.15X)=3.70 </span> </span> <span> <span> .6X+1-.15X=3.70 </span> </span> <span> <span> .45X=3.70-1 </span> </span> <span> <span> .45X=2.70 </span> </span> <span> <span> X=2.70/.45 </span> </span> <span> <span> X=6 number of dimes </span> </span> <span> <span> 2X=12 number of quarters </span> </span> <span> <span> 20-6-12=2 number of nickels </span> </span> </span></span>
