Answer:

x 2 +(29/10)x-(21/10) = 0 Add 21/10 to both side of the equation : x 2 +(29/10)x = 21/10 Now the clever bit: Take the coefficient of x , which is 29/10 , divide by two, giving 29/20 , and finally square it giving 841/400 Add 841/400 to both sides of the equation

Need the answer to this
Olegator [25]

Answer:

4.5 per package

Step-by-step explanation:

Though they give us 4 different pairs of values on the table, we only need 1 pair to solve this question. For simplicity, lets chose the pair of whole numbers:

54 : 12

This is the ration of servings to packages, or the servings per package.

To get our answer, we must find how many servings per 1 package, so we need to divide by 12:

\frac{54}{12} : \frac{12}{12}

   =

4.5 : 1

This means that there are 4.5 servings per 1 package!

Hope this helps!

A rectangle is 6cm longer than it is wide. It has a perimeter of 90 cm. Write down an equation to show this information.
kumpel [21]

Answer:

2(W + 6) + 2W = 90  where W = the width.

Step-by-step explanation:

The perimeter is 2L + 2W  where L = the length and W = the width of the rectangle.

The  length L = W + 6   so the equation is:

2(W + 6) + 2W = 90.
