Answer:

P = 3

Step-by-step explanation:

L = 4*w

P = 27 + w

P = 2*L + 2*w = 27 + w

2L = 2*(4w) = 8w

Put that into the perimeter formula (the first one.)

P = 8w + 2w = 27 + w

10w = 27 + w                        Subtract w from both sides

9w = 27                                Divide by 9

w = 27 / 9                          

w = 3

You should find the Length just so you can check it.

L = 4w

L = 4*3

L = 12

Check

P = 2L + 2w

P = 2*12 + 2*3 = 30

P = 27 + w

P = 27 + 3

P = 30 and everything checks.

A soccer player practices kicking the ball into the goal from halfway down the soccer field. The time it takes for the ball to g
lyudmila [28]
To find a constant velocity, we divide the distance by the time

We have:
Distance = 45  meters ⇒ The ball is kicked half way down the soccer field, so the distance that the ball traveled is 90 ÷ 2 = 45 meters
Time = 3 seconds

We have enough information to work out the velocity

v = s ÷ t
v = 45 ÷ 3 
v = 15 m/s

Which of the following tables shows the correct steps to transform x2 + 6x + 8 = 0 into the form (x − p)2 = q? [p and q are inte
Tanzania [10]
X^2+6x+8=0
To write the above in the form of (x-p)^2=q we proceed as follows:
i] Re-write the expression:
x^2+6x=-8
ii] Calculate for the vale of c.
c=(b/2a)²
given that:
b=6, and a=1
thus
c=(6/2*1)^2=9


iii]
Add 9 on both sides of the equation from i
x^2+6x+9=-8+9
simplifying we get:
x^2+6x+9=1
factoring the LHS we get:
(x+3)(x+3)=1
(x+3)²=1
The above is in the form of:
(x-p)²=q
where:
p=3 and q=1

A six-pack of soda costs $2.49, a 12-pack of soda costs $3.99, and a 24-pack of soda costs $5.49. Which pack has the lowest cost
Paladinen [302]
Solve:-

Find unit price per pack.  

6-Pack:-

2.49 ÷ 6 = <span>0.41
$</span><span>0.41 per can

12-pack:-

3.99 </span>÷ 12 = 0.33
<span>0.33 per can

24-pack:-

5.49 </span>÷ 25 = <span>0.22
</span><span>0.22 per can
</span>
The cheapest is 24-pack, because the unit price for that is the cheapest. After that pack is the 12-pack one because that is cheaper than the 6-pack. and last is the 6-pack. <span />
