Answer:

Step-by-step explanation:

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

4Comic+1 Nonfiction

4comic = 8y so 1 comic = 2y

1 nonfiction = (3+7y)+ 2y

1 nonfiction = 7y+2y+3 = 9y+3

total= 8y+9y+3 = 17y+3

if y=4

total = 17*4 +3 = $71

Simplify: ((1/x+h)-(1/x))/h

Darya [45]

$\frac{( \frac{1}{x}+h)- \frac{1}{x} }{h}= \\ = \frac{ \frac{1}{x}+h- \frac{1}{x} }{h}= \\ =\frac{h}{h}= 1$
Thank you.

Each cube in the prisms below has a volume of 1 cubic unit. which prism has a volume of 60 cubic units

mr_godi [17]

For A, 5x4x3=60
for B 5x3x2=30
for C 5x4x1=20
for D 5x4x2=40
hence, A has a volume of 60cubic units!

Using an arithmetic sequence, it is found that:

i) They collected 300 bottles on June 25th.

ii) The day was July 18th.

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n - 1)d$

In which $a_1$ is the first term.

In this problem, the sequence is: {417 ,404 ,391, .........}, hence the first term is $a_1 = 417$ , the common difference is d = -13, and the equation is:

$a_n = 417 - 13(n - 1)$

Item i)

They started on June 15th, hence June 25th is the 10th day, thus:

$a_{10} = 417 - 13(9) = 300$

They collected 300 bottles on June 25th.

Item ii)

This is n days after June 15th, for which $a_n = 1$ , hence:

$a_n = 417 - 13(n - 1)$

$1 = 430 - 13n$

$13n = 429$

$n = 33$

33 days after June 15th is July 18th.
