Answer: The answer is $(y+4)(y+2).$

Step-by-step explanation: The given polynomial expression is

$E=y^2+6y+8.$

We are given to factor the above polynomial expression completely. For that we need to find two numbers with sum 6 and product 8.

The factorisation is as follows:

$E\\\\=y^2+6y+8\\\\=y^2+2y+4y+8\\\\=y(y+2)+4(y+2)\\\\=(y+4)(y+2).$ .

Hence, factorised.

The age of father is a two digit number. If 5 is added to the double of the digit in the tenth place of father's age will be the

yuradex [85]

Answer:

The father is 50 and his son is 15.

Step-by-step explanation:

Double the tens digit of the father's age = 10

Plus 5 = 15 (the age of the son)

50 + 15 = 65 (the sum of their ages)

The reverse of the digits of the son's age is 51.

Subtract 1 = 50 (the age of the father)

Find f (2b^2) for (x)=x^2-4x

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

We are given the function:

$f(x) = x^2 - 4x$

And we want to find:

$\displaystyle f(2b^2)$

Substitute:

$\displaystyle f(2b^2) =(2b^2)^2 -4(2b^2)$

And evaluate:

$\displaystyle \begin{aligned} f(2b^2) &=(2b^2)^2 -4(2b^2) \\ &=(4b^4) +(-8b^2) \\ &= 4b^4 - 8b^2 \end{aligned}$

In conclusion, our answer is A.

If you take 2 1/2 tablets of meds 3 times a day for 10 days, how many tablets in total have you taken?

Alisiya [41]

This is how I solved it.
2.5 multiplied by 3 is 7.5, which equals how many she takes a day.
Then I multiplied 7.5 by 10 = 75. I did that because the meds are taken for 10 days.
Also if you added 7.5 ten times is also 75.

So my final answer is that 75 tablets have been taken in total.

A bird was sitting 16 feet from the base of an oak tree and flew 20 feet to reach the top of the tree. How tall is the tree?

Eddi Din [679]

Given:

A bird was sitting 16 feet from the base of an oak tree and flew 20 feet to reach the top of the tree.

To find:

The length of the tree.

Solution:

A bird was sitting 16 feet from the base of an oak tree.

Vertical distance between bird and base = 16 feet

Then the bird flew 20 feet to reach the top of the tree.

Now, the vertical distance between bird and base = (16+20) feet

So, length of the oak tree is it the sum of 16 feet and 20 feet.

$\text{Length of the oak tree}=16+20$ feet

$\text{Length of the oak tree}=36$ feet

Therefore, the length of the oak tree is 36 feet.
