Answer:
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
Step-by-step explanation:
Formulas are used to factorize the polynomials.
In the given question, we can see a difference of squares
the difference of squares can be factorized using the formula
Here a^2 and b^2 are squares and factorized as sum and difference of numbers.
So in the given options,
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
Answer:
State A = oxygen; State B = juice
Option 3
Step-by-step explanation:
Given:
State A: Changes shape and volume
State B: Changes shape but not volume
Multiple Choice options:
State A = juice; State B = block of wood
State A = hydrogen; State B = block of wood
State A = oxygen; State B = juice
State A = air; State B = neon
The three states of matter are
Solid - Does not change shape or volume (like ice)
Liquid - Changes shape but not volume (like water)
Gas - Changes shape and volume (like water vapour in air)
State A must be a gas.
State B must be a liquid.
Eliminate the choice where state A is not a gas.
State A = juice; State B = block of wood
Juice is a liquid, like water.
State A = hydrogen; State B = block of wood
State A = oxygen; State B = juice
State A = air; State B = neon
Find the choice where state B is a liquid.
State A = hydrogen; State B = block of wood
State A = oxygen; State B = juice
State A = air; State B = neon
Incorrect State B:
Block of wood - solid
Neon - gas
