Written in factored form, the binomial a^2b - ab2 is equivalent toA. ab(a - b)
B. (a - b)(a + b)
C. a^2(b-b^2)
D. a^2b^2(b - a)

Answers

Answer 1
Answer:

The factor of the expression into an equivalent form a²b - (ab)² would be; C  a^2(b-b^2)

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to factor the expression into an equivalent form a²b - (ab)²

This expression could also be given by;

a²b - (ab)²

Now, we know that:

a²- b² = (a + b) (a - b)

Now plug the values then we get;

a^2(b-b^2)

Hence, the factor of the expression into an equivalent form a²b - (ab)² would be; C  a^2(b-b^2)

Answer 2
Answer: B.(a-b)(a+b)
Because the radius of the numerical number would be hostile once intercepting the equivalent factor would be a^2(b-b^2)

Mary and ann made drinks for a picnic. one used 3 cans juice concentrate and 8 cans water. the other 5 cans juice concentrate and 12 cans of water. which was juicier and why

Answers


I would think that it would be the 3:8 one because if you do the math, 8-3 is 5 and 12-5 is 7. The only reason Im doing it this way is because its the only way I can set it up.

so you have more of a difference with the 12:5 one and less of a difference with the 3:8.

Tasha plants to tile the floor in her room with square tiles that are 1/4 foot long. will she use more or fewer tiles if she only able to purchase square tiles that are 1/3 foot long? EXPLAIN

Answers


1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.

1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.

The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers.  So she won't need as many 1/3-ft tiles to cover the floor
in her room.  She will use fewer of those.

Answers

the clydesdale drinks 840 Gallons of water in 28 days.
Since a clydesdale drinks 120 gallons every 4 days, u have to divide 28 by 4:
28÷4=7
Now u multiply 7 by 120 for da answer:
7(120)=840.

Sara Just Turned 18 Years Old. She Spent 4/9 Of Her Life Living In Rochester,NY. How Many Years Did Sara Live In Rochester?

Answers

1/9 of 18 is 2.

So 4/9 of 18 = 4*2 = 8

So Sara lived in Rochester for 8 years.

8 years

Further explanation

Given:

Sara just turned 18 years old.

She spent (4)/(9) of her life living in Rochester, NY.

Question:

How many years did Sara live in Rochester?

The Process:

From the information above, we make a suitable diagram as follows:

\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = ? \ years

Four of the nine parts are the question. The nine full parts below are Sara's ages.

\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot}\boxed{\cdot} = 18 \ years

Let us calculate how many years did Sara live in Rochester.

  • \boxed{ \ 9 \ parts = 18 \ }
  • \boxed{ \ 4 \ parts = ? \ }

\boxed{ \ = (4)/(9) * 18 \ }

We crossed out 9 and 18.

\boxed{ \ = 4 * 2 \ }

Thus Sara has lived in Rochester for\boxed{\boxed{ \ 8 \ years \ }}

- - - - - - - - - -

Quick Steps:

\boxed{ \ = (4)/(9) * 18 \ }

\boxed{ \ = 4 * 2 \ }

\boxed{\boxed{ \ 8 \ years \ }}
