Distribute 4 over the parentheses:-

4(x - 2) = 4x - 8  which is identical to the right side.

Yes  - this is always true for any values of x,  and its called an identity.

Yes, 4(x-2) is 4 times x-2 which using the distributive property gives you 4x-8 because 4 times x is 4x and 4 times -2 is -8 so you would always get 4x-8

WITCHER [35]

Answer:

0.025 Kg/ cm²

Step-by-step explanation:

if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable

the equation that represents inverse proportion :

y = \frac{b}{x}

where b = constant of proportionality

to determine the answer in this question :

1. determine constant of proportionality

200 = k / 32

k = 6400

2. Determine the amount of pressure using the constant of proportionality

256, 000 = 6400 / pressure

pressure = 6400 / 256, 000 = 0.025

Lorico [155]

Answer:

Total area of the two rooms   =   (width1length1) +   (width2length2)

Step-by-step explanation:

The area of the rectangular shape is given by = Length * breadth

Therefore the area of the two rooms can be calculated using the above formula when the variables lengths and widths are given.

Area 1= Area of the first room = length * breadth=  (width1length1)

Area 2=Area of the second room = length * breadth=  (width2length2)

Total area of the two rooms = Area1 + Area 2

                                         =   (width1length1) +   (width2length2)
