What is -4√12+√75 in the simplest radical form?

nekit [7.7K]

Answer: -3 $\sqrt{3}$

Step-by-step explanation:

-4 $\sqrt{12}$ + $\sqrt{75}$

$\sqrt{12}$ can be written as $\sqrt{4}$ x $\sqrt{3}$

which is the same as 2 $\sqrt{3}$

Also , $\sqrt{75}$ can be written as $\sqrt{25}$ x $\sqrt{3}$ , which is the same as 5 $\sqrt{3}$

Substituting into the main question , we have

-4 (2 $\sqrt{3}$ ) + 5 $\sqrt{3}$

= -8 $\sqrt{3}$ + 5 $\sqrt{3}$

= -3 $\sqrt{3}$

If f(x)=16x-30 and g(x)=14x-6, for which value of x does (f-g)(x)=0

tamaranim1 [39]

Answer:

x=12

Step-by-step explanation:

f(x)=16x-30 and g(x)=14x-6

(f-g)(x)=0

f(x)=16x-30 -(14x-6)

Distribute

= 16x -30 -14x +6

Combine like terms

= 16x-14x -30+6

2x-24

Set this equal to zero

2x-24 =0

Add 24 to each side

2x-24 +24=0+24

2x=24

Divide by 2

2x/2 =24/2

x = 12

Answer :

<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3>

Step-by-step explanation:

<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3><h3>For :</h3>

We know that $The average (Mean)=\frac{sum of the observations}{Number of observations}$
$Mean=\frac{\sum x}{N}$ where N is the number of observations

<h3>Therefore the average of a distribution is known as Mean.</h3>

lesya692 [45]

Answer:

Melanie's account balance now is $3182.87.

Step-by-step explanation:

Given:

Amount of money in her account = $3106.12

Amount deposited on Thursday = $85

Amount spent for lunch on Friday = $8.25

We need to find the remaining balance in Melanie's account.

Solution:

Now we know that;

Remaining balance in her account is equal to Amount of money in her account plus Amount deposited on Thursday minus Amount spent for lunch on Friday.

framing in equation form we get;

Remaining balance in her account = $\$3106.12 +\$85 - \$8.25=\$3182.87$

Hence Melanie's account balance now is $3182.87.
