Answer:

d = -60

Step-by-step explanation:

Given:

-1/4d - 2/5d = 39

-5d-8d/20 = 39

-13/20d = 39

Divide both sides by -13/20

d = 39 ÷ -13/20

= 39 × -20/13

= -60

d = -60

A cube has an edge length of 6 cm. It is to be enlarged by a scale factor of 4. What is the surface area ratio of the enlarged c
Andru [333]
The surface area ratio of the enlarged cube to the original cube is 16:1, or as a fraction, 16/1.

If the scale factor is 4, the edge length of the enlarged cube is 24 cm.
(6 × 4 = 24)

To find the surface area of a cube, you can use the formula SA=6a^2, where a is equal to the edge length of the cube.

First, I will solve for the surface area of the original cube. 

SA = 6 × 6²
SA = 6 × 36
SA = 216

Next, I will solve for the surface area of the enlarged cube.

SA = 6 × 24²
SA = 6 × 576
SA = 3456

To find the ratio, we divide the original cube's surface area from the enlarged cube's surface area.

3456 ÷ 216 = 16

The surface area ratio of the enlarged cube to the original cube is 16:1, or as a fraction, 16/1.
