6. If you increase all dimensions of an object by a scale factor of 4, how much would the volume increa
a.
4 times longer
c.
8 times longer
b.
64 times longer
d.
16 times longer
No

4. 16 times longer

5. 4 times longer

6.  64 times longer

Step-by-step explanation:

Solving (4):

Let the length and with of the object be x and y

Apply Scale Factor of 4

Divide Area₂ by Area₁

Hence;

The surface area will increase 16 times longer

Solving (5):

Let the length and with of the object be x and y

When the object is increased by a scale factor of 4;

It means that the Area is increased by a scale factor of 4

i.e.

Divide Area₂ by Area₁

Hence;

The surface area will increase 4 times longer

Solving (6):

Let the length, width and height of the object be x, y and z

Apply Scale Factor of 4

Divide Volume₂ by Volume₁

Hence;

The volume will increase by 64 times

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
