area of base=6×6=36 m²

surface area of four walls=4×6×12=144 m²

area of top= area of four triangles=4×1/2×6×5=60 m²

total surface area=36+144+60=240 m²

Which value of d is a solution to equation 2.2d + 5.4= 12

ryzh [129]

Hello!

Answer:

d=3

*The answer must have a positive sign.*

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you multiply by 10 from both sides of an equation.

$2.2d*10+5.4*10=12*10$

Then, you had to refine the problem down.

$22d+54=120$

Next, you subtract by 54 from both sides of an equation.

$22d+54-54=120-54$

Simplify.

$22d=66$

You can also divide by 22 from both sides of an equation.

$\frac{22d}{22}=\frac{66}{22}$

And finally, simplify and solve. You can also divide by the numbers.

$66/22=3$

Final answer: → $d=3$

Hope this helps!

Thanks!

Please help, I am terrible at math

Zarrin [17]

Answer:

the correct option is D (12 units, 14 units, 10 units)

Step-by-step explanation:

P= 36

2t + 2 + 2t + 4 +2t = 36

combine like terms

6t + 6 = 36

subtract 6 from both sides

6t = 30

30/6 = 5

T = 5 so plug the t in the other equations

2(5) + 2 = 10 + 2 = 12

2(5) + 4 = 10 + 4 = 14

2(5) = 10

To check combine all the numbers above and you would get 36
