What is the first step in solving the quadratic equation x^2=9 over 16
nikdorinn [45]

Answer:

"Take the square root of both sides of the equation"

A is correct

Step-by-step explanation:

We are given quadratic equation

We need to solve for x. We have to isolate x here.

Here square on x. So, first we get rid of square.

Taking square root both sides to get rid of square.

For example:

a2=25

sqare a2  = +- sqare 25

x2=9/16 to solve for x

sqare x2 +- sqre 9725

x=+- 3/5

Hence, "Take the square root of both sides of the equation"

Hi guys really need help w/ this problem will give brainllest for the first person
Vladimir [108]

Answer:

There are 6 nickels, 10 dimes and 13 quarters.

Step-by-step explanation:

number of nickels = n

number of dimes = n+4

number of quarters = (n+4)+3 = n+7

express total amount in cents $4.55 = 455 cents

express total in cents by multiplying quantities of coins by value and adding them up.

455 = 5*n + 10*(n+4) + 25*(n+7) 455 = 5n + 10n + 40 + 25n + 175 240 = 40n n = 6

so number of nickels = 6.

number of dimes = number of nickels + 4 = 6+4 =10

number of quarters = number of dimes + 3 = 10+3 = 13

There are 6 nickels, 10 dimes and 13 quarters.

List the next four multiples of the fraction 7/12
choli [55]
<h2>Hello!</h2>

The answer is:

\frac{14}{12},\frac{21}{12},\frac{28}{12},\frac{35}{12}

<h2>Why?</h2>

Let's explain with an example the definition of a multiple.

Multiple of the number 1 are: 1, 2, 3, 4, 5 and so...

Multiple of the number 3 are: 3, 6, 9, 12, 15 and so...

A multiple of a number is the repeated sum of itself, from the example:

Multiple of the number 1 are: Itself, (1+1), (1+1+1), (1+1+1+1), (1+1+1+1+1) and so...

Therefore,

Multiple of \frac{7}{12} are:

\frac{7}{12} =\frac{7}{12}(itself)=\frac{7}{12}*1 \\\\\frac{14}{12}= \frac{7}{12}+\frac{7}{12}=\frac{7}{12}*2\\\\\frac{21}{12}=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}=\frac{7}{12}*3\\\\\\\frac{28}{12}=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}=\frac{7}{12}*4\\\\\frac{35}{12}=\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}+\frac{7}{12}=\frac{7}{12}*5

Have a nice day!
