Answer:

h=\frac{1}{6}

Step-by-step explanation:

Given:

A=\frac{1}{2h} (B+b)\\

A=21, B=2, b=5 ,h= ?

We have to find the value of  'h'

So, putting the given values in the equation to find the value of 'h'.

          A=\frac{1}{2h} (B+b)

Implementing the given values in the given equations:

         

                              21=\frac{1}{2h}(2+5)\\\\ 21=\frac{1}{2h} (7)\\\\\frac{1}{2h}=\frac{21}{7}\\\\  \frac{1}{2h}=3 \\\\h=\frac{1}{6}

So, the value of 'h' is

                       h=\frac{1}{6}

Esmerelda bought a bag of jelly beans. There were 24 green jelly beans, which made up 8%, percent of all the jelly beans in the
Margarita [4]
So, let's look at the problem once again.

8%, or 8/100 of the bag were green jelly beans.

Let's see what we can do to find out a number of other jelly beans, not including the green ones.

We know that 92% of jelly-beans are not green.

92% is 11.5 times more than 8%
(92/8)

24 (or 8%) times 11.5 = 276

276 - number of jelly beans that are not green.

276 plus 24 = 300.

Answer: 300 jelly beans were in one bag.

Hey:) can you please help me posted picture of question
Kryger [21]
To expand the given expression we proceed as follows:
(6x²-2x-6)(8x²+7x+8)
=6x²(8x²+7x+8)-2x(8x²+7x+8)-6(8x²+7x+8)
=48x⁴+42x³+48x²-16x³-14x²-16x-48x²-42x-48
putting like terms together:
48x⁴+(42x³-16x³)+(48x²-48x²)+(-16x-42x)-48
=48x⁴+26x³+0x²-58x-48
hence the answer is:
48x⁴+26x³-58x-48
