Solve S= lw + wh+ lh for h. Hint: Use the distributive property to factor out h. the 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

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

aleksklad [387]

Answer:

C. 60 blue marbles

Step-by-step explanation:

10 marbles are taken out of the bag.

6 marbles taken out are red.

So the other 4 marbles taken out are blue.

200 ÷ 4 = 50

and 50 is close to 60.

Let me know if this helps!

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.

Question 1:

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

Question 2:

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
