1)  sin^6 a + cos^6 a = (sin^2 a)^3 + (cos^2 a)^3
2) a^3 + b^3 = (a+b) (a^2 - ab + b^2)

Choose the correct answer.

Answer:


Step-by-step explanation:

Since we are given that

7 gallons final mixture contains 50% lemon and 50% lime juice.

⇒50% of 7

⇒\frac{50}{100} *7

⇒\frac{1}{2} *7

⇒3.5

Thus , 7 gallons final mixture contains <u>3.5 gallons lemon</u> and <u>3.5 gallons lime juice. </u>

Now, Initial mixture contains 30% lemon juice and 70% lime juice .

This means  

10 gallons initial mixture contains <u>3 gallons lemon juice </u>and <u>7 gallons lime juice . </u>

So, they have 3 gallons of lemon juice  and 7 gallons of lime juice

But they require 3.5 gallon of lemon juice and 3.5 gallons lime juice. to make 7 gallon of final mixture

So, from the initial 10 gallons of mixture

We can take take 50 % of 10 gallons i.e.

5 gallons initial mixture contains<u> 1.5 gallons lemon juice</u> and <u>3.5 gallons lime juice</u> .

Thus require 3.5 gallons of lemon juice but they have 1.5 gallons of lemon juice

So, they require 3.5-1.5=2 gallons of lemon juice

Hence 2 gallons lemon juice is to be added with this mixture to make the final mixture containing 50% lemon and 50% lime juice.

50 PTS PLEASE HELP ASAP Find the product of 2x4(2x2 + 3x + 4).
bulgar [2K]
2x⁴(2x² + 3x + 4)

Simplify.

4x⁶ + 6x⁵ + 8x⁴   ==> The second answer choice.

We know this because :

Multiply 2x⁴ with 2x²

2x⁴ × 2x² = 4x⁶

Then, do :

2x⁴  × 3x = 6x⁵

Then, finally, do :

2x⁴  × 4 = 8x⁴

So, our answer looks like this :

4x⁶ + 6x⁵ + 8x⁴

a gardener has 27 pansies and 36 daisies he plants an equal number of each type of flower in each row what is the greatest possi
miskamm [114]
We have to find the greatest possible number of each type of flower
( pansies and daisies ) in each row.
We have to find the GCF for 27 and 36.
27 = 9 * 3
36 = 9 * 4
So :  GCF ( 27, 36 ) = 9
We will have 9 pansies in 3 rows and 9 daisies in 4 rows.
Answer:
The greatest possible number of pansies in each row is 9.
