Using the quadratic formula the 2 zeros of the function (there have to be 2 cuz it's a quadratic) are x = -1/2 and -5 1/2

julia puts her stickers into arrays in an album. some of her stickers are animal stickers. there are a different number of stick
lina2011 [118]

The total number of stickers :

Page 1 : 28

Page 2 : 24

Page 3 : 72

Page 4 : 48

<h3>Further explanation </h3>

There are several properties in integer multiplication operations

  • 1. closed property

Multiplication between integers will produce integers too

  • 2. commutative property

a x b = b x a

  • 3. associative property

ax (bxc) = (axb) xc

  • 4. identity

ax1 = 1 x a = a

  • 5. distributive  property

* addition

ax (b + c) = axb + axc

* substraction

ax (b-c) = axb - axc

We can use facts to solve multiplication problems

for example :

6 x 7 = (5 x 7) + ( 1 x 7) = 42

we can break facts with 6 into  5s and 1s facts from multiplication above

julia puts her stickers into arrays in an album

From picture (attached) we can find the total number of stickers on each page with 1s,2s,3s and 5s facts

  • Page 1 : 4 x 7 = (2 x 7) + ( 2 x 7) = 14 + 14 = 28
  • Page 2 : 4 x 6 = (1 x 6) + (3 x 6) = 6 + 18 = 24
  • Page 3 : 8 x 9 = ( 3 x 9) + (5 x 9) = 27 + 45 = 72
  • Page 4 : 8 x 6 = (3 x 6) + (5 x 6) = 18 + 30 = 48

Need help on solving this ?

For the first question, simply plug in the value of 3 into the polynomial question. The final answer is your volume of the hot water tub.

For the second question, you can figure out that x = -5 is not a real root because it does not touch or cross the x axis.

If it does it would be an solution.

Answer:

I would say 6:12.

Step-by-step explanation:

it is equivalent to 12:24 because 12/2= 6 and 24/2 = 12 so 6:12 is your answer!

The area of the rectangle is 50 yd2. What is the formula that shows the length of side y?
AVprozaik [17]
Let L = lengthLet W = width Length is 5 yd less than twice the width  ==>  L = 2*W - 5 Area is 52 yd^2  ==>  52 = L*W Substitute the value for L from the 1st equation into the 2nd equation 
52 = (2*W - 5) * W52 = 2*W^2 - 5*W0 = 2*W^2 - 5*W - 52 0 = (2W - 13)*(W + 4) 2W - 13 = 0  or  W + 4 = 0W = 13/2      or  W = -4 Width cannot be negative so discard W = -4  W = 13/2  ==>  L = 2*(13/2) - 5 = 13 - 5 = 8  So the width is 13/2 yards and the length is 8 yards  Check:  2*(13/2) - 5 = 13 - 5 = 8             (13/2)*8 = 4*13 = 52 yd^2
