Suppose that the Domino's short side measures l units<span>. Then it's long side measures 2l</span>  units, and the Domino's total perimeter is 6l=60. Thus l =10 and<span> the Domino's area is 10 x 20=200</span><span> square units.</span>

Answer:

200

Step-by-step explanation:

So say the dominoes' short side is x. Then the long side is 2x, so altogether there is 6x. So 6x=60, so x=10. So the area is 10*(10*2), which is 10*20 which is 200.

Write an equation for the 4th degree polynomial graphed below. Use k if your leading coefficient is positive and −k if your lead
Afina-wow [57]
Ho ho ho, lets get this party started
ok so I'm just really excited to use this stuff that I just learned

so

multiplicites
if a root or zero has an even multilicity, the graph bounces on that root
if the root or zero has an odd multiplicty, the graph goes through that root

so
roots are
-1
2
4
multiplicty is how many times it repeats
2 has even multiplity
we just do 2 is odd and 1 is even so
for roots, r1 and r2, the facotrs would be
(x-r1)(x-r2)
so
(x-(-1))^1(x-2)^2(x-4)
(x+1)(x-2)^2(x-4)
this is a 4th degre equaton
normally, it is goig from top right to top left
it is upside down
theefor it has negative leading coefient



y=-k(x+1)(x-4)(x-2)^2

If 300 boxes of medical sponges cost $25.00, how many boxes can you purchase for $0.50?
nikdorinn [45]
You can purchase 6 boxes of medical sponges for $0.50.

Step 1:
Divide 300 by 25.00
300/25= 12
So you get 12 boxes for 1 dollar.
We have 50 cents.

Step 2:
Multiply 12 by 0.50
12*.5 = 6
So you can buy 6 boxes for $0.50.

Hope this helps you! (:

Ivenika [448]

The high temperature was 2 degrees Fahrenheit in the town that day.

Step-by-step explanation:

Given,

Low temperature in Leroy's town = -4 degree Fahrenheit

Difference between low and high temperature = 6 degrees Fahrenheit

Equation used to find high temperature h;

h-(-4)=6

Solving the equation

h+4=6\\h=6-4\\h=2

The high temperature was 2 degrees Fahrenheit in the town that day.
