Solve S= lw + wh+ lh for h. Hint: Use the distributive property to factor out h.<br> the<br> vcloc
Ostrovityanka [42]

Answer:

{ \rm{S = lw + wh + lh}}

• Group the h terms by organised term arrangement :

{ \rm{S = (wh + lh) + lw}}

• Then using distributive property, factorise out the value h so that the reverse is true.

{ \rm{S = h(w + l) + lw}}

• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:

{ \rm{S = h(w + l) + h( \frac{lw}{h} )}} \\

• finally, completely factorise out the value h

\hookrightarrow \: \: { \boxed{ \boxed { \rm{ \:  \: S = h(w + l +  \frac{lw}{h} ) \:  \: }}}}

6 marbles taken out are red.

So the other 4 marbles taken out are blue.

200 ÷ 4 = 50

and 50 is close to 60.

Given a sequence is defined by the explicit definition tn=n^2+n.... (questions attached)
s2008m [1.1K]

Question 1: The correct answer is  Option 3: 20

Question 2: The correct answer is Option 3: 27

Step-by-step explanation:

We put the term number as value of n in explicit formula to find the term.

<u>Question 1:</u>

Given

t_n=n^2+n

To find t4, we will put t=4 in explicit formula

t_4=(4)^2+4\\t_4=16+4\\t_4=20

The correct answer is  Option 3: 20

<u>Question 2:</u>

Given, the explicit formula

t_n=2^n-n

We have to find the 5th term, putting n=5 in the explicit formula

t_5=2^5-5\\=32-5\\=27

The correct answer is Option 3: 27
