What are the measurements of the little 2 small cube things on each side, better yet what's the surface area? Thank you

Arisa [49]

Answer:

166 units²

Step-by-step explanation:

We know that:

W = 7
L = 5
H = 4

Surface area is the area of the faces of the cuboid.

Work:

=> 2(7 x 4) + 2(5 x 4) + 2(5 x 7)
=> 2(28) + 2(20) + 2(35)
=> 56 + 40 + 70
=> 166 units²

Hence, Option C is correct.

Hoped this helped.

Prove the polynomial identity.

aleksandr82 [10.1K]

Explanation:

Since we have given that

$(2x+1)^2-2(2x+1)$

Now, we have to prove it as

$(2x+1)(2x-1)$

Now, start the iterations:

$(2x+1)^2-2(2x+1)\\\\=4x^2+1+4x-4x-2\\\\=4x^2+1-2\\\\=4x^2-1\\\\=(2x)^2-1\\\\=(2x+1)(2x-1)$

So, first blank will be filled with

$4x^2+4x+1$

Second blank will be filled with

$4x^2-1$

Hence proved.

Gelneren [198K]

Answer:

$29$

Step-by-step explanation:

Let x be the original price.

( 1 - 20% ) x = 23.2

$0.8x = 23.2$

$\frac{0.8x}{0.8} = \frac{23.2}{0.8}$

$x = 29$
