3-(x-3)=25 solve the equation

Mathematics
1 answer:
kherson [118]3 years ago
7 0

Answer:

x= -19

Step-by-step explanation:

3-(x-3)=25

Distributive property to cancel out the paranthesis

3-x+3=25

Add the number

6-x=25

Subtract 6 on both sides

-x=19

Divide by -1 on both sides so the x to eliminate the negative sign

x=-19

The standard formula for the volume of a rectangular pyramid is . If the pyramid is scaled proportionally by a factor of k, its
PolarNik [594]

Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The volume of a rectangular pyramid is equal to

V=\frac{1}{3}LWH

where

L is the length of the rectangular base

W is the width of the rectangular base

H is the height of the pyramid

If the pyramid is scaled proportionally by a factor of k

then

the new dimensions are

L=kL

W=kW

H=kH

substitute and find the new Volume V'

V'=\frac{1}{3}(kL)(kW)(kH)

V'=\frac{1}{3}(k^{3})LWH

V'=(k^{3})\frac{1}{3}LWH

V'=(k^{3})V

The new volume is equal to the scale factor k elevated to the cube multiplied by the original volume
