6 * 2.5 = 15 That’s the area of the base

2.5 * 4 = 10
10 * 2 = 20
That’s the area of the 2 smaller sides

6 * 4 = 24
24 * 2 = 48
That’s the area of the 2 larger sides

Then you add all the dimensions together.

15+20+48 = 83.

So, the final equation is (6*2.5) + 2(2.5*4) + 2(6*4) = 83

What is the value of the expression below when z = • 3?<br> 622 + 2z + 10
inn [45]

Answer:

632.6

Step-by-step explanation:

Z = .3 right? It looks weird on my screen

Anyway, if z is .3 than this is how to solve

First you plug in 0.3 where the z would go, making the expression 622 + 2(0.3) + 10. Then you solve! (below)

622 + 2(0.3) + 10.

622 + 0.6 + 10.

622 + 10 + 0.6

632 + 0.6

632.6

I hope this helped! If you have any questions, feel free to message me :)

Simplify 27x^7y^2/9x^6y^5
solmaris [256]

Answer: x/y^3

Step-by-step explanation:

So you divide 27/9 which is 3. Then it ix x^7-x^6=x. And then it is y^2-y^5=y3

27*x*x*x*x*x*x*x*y*y/9*x*x*x*x*x*x*y*y*y*y*y

Doing this makes it easier so you cross each variable out for each one in both sides. 3x/y^3 would be your answer.
