Paha777 [63]

Complete Question:

A closed box has a square base with side length L feet and height h feet. Given that the volume of the box is 39 cubic feet, express the surface area of the box in terms of L only.

Answer:

$A = \frac{156}{L} + 2L^2$

Step-by-step explanation:

Given

$Volume = 39ft^3$

Required

Express the surface area in terms of L

Because the box has a square base:

The volume is:

$Volume = Base\ Area * Height$

Where

$Base\ Area = L * L$

So, we have:

$Volume = L * L * H$

Substitute 39 for Volume

$39= L * L * H$

$39= L^2 * H$

Make H the subject

$H = \frac{39}{L^2}$

The surface area (A) of a box with square base is:

$A = 2(LH + LH + L^2)$

$A = 2(2LH + L^2)$

Open bracket

$A = 4LH + 2L^2$

Substitute $\frac{39}{L^2}$ for H

$A = 4L * \frac{39}{L^2} + 2L^2$

$A = \frac{4L *39}{L^2} + 2L^2$

$A = \frac{4*39}{L} + 2L^2$

$A = \frac{156}{L} + 2L^2$

–2x(–3x 2 y)(2y) = ? A. 12x 3y 2 B. –3xy2 C. 3xy2 D. –12x 3y 2

Rina8888 [55]

Answer:

Option A - $-2x(-3x^2y)(2y)=12x^3y^2$

Step-by-step explanation:

Given : Expression $-2x(-3x^2y)(2y)$

To find : Solve the expression ?

Solution :

Step 1 - Write the expression

$-2x(-3x^2y)(2y)$

Step 2 - Multiply the first two bracket in multiplication if base are same power get added and apply symbol rule of multiplication $(-)(-)=(+)$

$=(6x^3y)(2y)$

Step 3 - Again multiply the bracket,

$=12x^3y^2$

Therefore, Option A is correct $-2x(-3x^2y)(2y)=12x^3y^2$
