What value should be added to the expression to create a perfect square?
Shalnov [3]
Let's take a look at a perfect square trinomial.

(x+7)^2

We can distribute this expression to get x^2+14x+49.

An important relation to recognize here is that the constant is the square of half of the x value.

Now, if we wanted to add a number to x^2+16x to make a perfect square trinomial, we could have the value of x and then square it.

Half of 16 is 8, and 8 squared is \boxed{64}

bearhunter [10]

Answer:

\frac{1}{2}  \: or \: 0.5

Step-by-step explanation:

\frac{5}{7}  \times  \frac{14}{20}  =  \frac{5 \times 14}{7 \times 20}

It can be also written as -

=  >  \frac{5 \times 14}{20 \times 7}  =  \frac{5}{20}  \times  \frac{14}{7}  =  \frac{1}{4}  \times 2 =  \frac{1}{2}

Four friends hosted a Graduation party: Genesis spent $21 for drinks, Mya spent $25 for food, Alina spent $16 for invitations, a
Naya [18.7K]

Answer:

Alina owes $4 to Mya and Mylana owes $1 to Mya and $1 to Genesis.

Step-by-step explanation:

As they want to share the party expenses equally, first you have to add all the expenses and divide them by 4 people to know the amount that each person has to pay:

$21+$25+$16+$18= $80/4= $20

As everyone has to pay $20 for the party expenses, we can see that Genesis spent $1 more and Mya $5 more, so they have to get the money back from the other 2 people.

Alina owes: $20-$16= $4. She owes $4 to Mya as she will pay the entire amount she owes to one person and Mya has to get $5 back.

Mylana owes: $20-$18= $2. She would have to pay $1 to Mya to complete the $5 she had to get back and $1 to Genesis.
