Plug 4 in for every x

(3*4)-4=8
(4^2)-1=15 [(4^2) is 4*4]
(2*(4^2))-15= 15 [because of PEMDAS the exponent comes first and then multiply by 2 then subtract]

Perimeter is the sum of the lengths so add up all the sides from above
8+15+15=38

Answer:

x =   \frac{3}{ \sqrt{2} }

Step-by-step explanation:

{x}^{2}  +  {x}^{2}  =  {3}^{2}  \\ 2 {x}^{2}  = 9 \\  {x}^{2}  =  \frac{9}{2}  \\ x =  \frac{3}{ \sqrt{2} }  \\ x = 2.121

Please tell me this, please! ASAP!

Answer:

a)  C = 250 + 1.25n

b) 1800

c) 300

Step-by-step explanation:

a) To write the equation for these problems, let's establish the constant, $250, since we are given that $250 is a FIXED cost, meaning no matter how many brochures we print, we will have to pay $250. Then, we have to pay $1.25 for each brochure, so for n amount of brochures, so we have 1.25*n. Putting it together, we have the fixed cost + the cost of producing n brochures, C = 250 + 1.25C

b) The cost of printing 2500 brochures can be found by pluggin number into the equation above. C = 250 + 1.25*2500 = $1800

c) This is the opposite question, since 625 is the final cost, we plug it into the final cost, 625 = 250 + 1.25*n. Solving gives n = 300

Let's see what to do buddy...

Step-by-step explanation:

first \:  \:  \:  \frac{1}{4} \:  \:  \:of \:a \: song \: needs \:  \frac{1}{8} \:  \: minute. \\  \\ second \:  \:  \:  \frac{1}{4} \:  \: of \: a \: song \: needs \:  \frac{1}{8} \: minute \: too. \\  \\ also \: the \: third \: and \: fourth \:  \:  \:  \frac{1}{4} \:  \:  \:  of  \: a \: song \: need \:  \frac{1}{8} \: minute \: . \\  \\ so \: we \: have \: completly \: have \: 4 \times  \frac{1}{8} \\  \\ which \: means \: edi \: needs \: 4 \times  \frac{1}{8}  =  \frac{4}{8} =  \frac{1}{2} \:  minute \: to \: play \: all \: the \: song.

The terms in the sequence decrease by the same amount each time:
luda_lava [24]

Answer:the nth term of the sequence, Tn= -3n +12

Step-by-step explanation:

The nth term of an arithmetic progression is given as

Tn=  a+ (n-1) d

where a= first term

and d = common difference

In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that  the number is decreasing by 3

The first term, a= 9

and common difference, d = -3

using our formulae

Tn=  a+ (n-1) d

Tn= 9 + ( n-1) -3

Tn=9- 3n+ 3

Tn= -3n +12
