simplify each radical, then add or subtract. sqrt12 +sqrt27​

Answers

Answer 1

Answer:

[tex]5\sqrt{3}[/tex]

Step-by-step explanation:

simplify sqrt(12): [tex]\sqrt{12} = \sqrt{4 * 3} = \sqrt{4} * \sqrt{3} = 2 * \sqrt{3} = 2\sqrt{3}[/tex]

simplify sqrt(27): [tex]\sqrt{27} = \sqrt{9 * 3} = \sqrt{9} * \sqrt{3} = 3 * \sqrt{3} = 3\sqrt{3}[/tex]

substitute into original equation: [tex]\sqrt{12} + \sqrt{27} = 2\sqrt{3} + 3\sqrt{3}[/tex]

factor out sqrt(3): [tex]\sqrt{3} * (2 + 3)[/tex]

simplify: [tex]\sqrt{3} * 5 = 5\sqrt{3}[/tex]

3x6= 18 x=1 so 18x1=18
18+2=20

is 3:4 and 9:16 equivalent

Answers

For comparison, we must make their denominators equal by taking their least common multiple(LCM) . The LCM of 4 and 16 is 16.

So, 3/4 = 3*4 / 4*4 = 12/16

Now, 12/16 > 9/16 i.e. 3/4 > 9/16

So. 3:4 is larger between 3:4 and 9:16.

Answer:

No

Step-by-step explanation:

Equivalent ratios are created by multiplying/ dividing the parts by the same value.

3 : 4 ( multiply both parts by 4 )

= 12 : 16 not 9 : 16

f(g(x)) = -2x + ????

Answers

Answer:

f(g(x)) =  - 10x - 13

Step-by-step explanation:

Given functions:

f(x) = 5x +7

and

g(x) = -2x - 4

Work out the composite f(g(x)):

f(g(x)) = f( -2x - 4) = 5( - 2x - 4) + 7 = -10x - 20 + 7 = - 10x - 13

Answer:

f(g(x)) = -10x - 13

???? = - 8x - 13

Step-by-step explanation:

f(x) = 5x +7

and

g(x) = -2x - 4

f(g(x)) = f(-2x - 4) = 5(-2x - 4) + 7

f(g(x)) = -10x - 20 + 7

f(g(x)) = -10x - 13

f(g(x)) = -2x - 8x - 13

1. Let the four consecutive numbers be x, x+1, x+2, x+3

The sum of four consecutive number is already given to us = 70

Therefore

⇒(x)+(x+1)+(x+2)+(x+3)=70  

We need to combine x as we have four x terms in the equation. The next step is to get all of the x’s on one side of the equation and all the numbers on the other side. The same rule applies – whatever you do to one side of the equation, you must do to the other side as well!

⇒4x+6=70⇒4x=64⇒x=16

So, the four numbers are 16, 17, 18 and 19.

Hence, the greatest number among them is 19.

x = 10

Step-by-step explanation:

x^2 -14x + 40 = 0 ----> factor form

(x - 10)(x - 4) = 0 ---> separate equations

x - 10 = 0 ---> add 10 on both sides

x = 10

x - 4 = 0 ---> add 4 on both sides

x = 4

Answer:

small x= 4

large x= 10

Step-by-step explanation:

hello there!

x^2-14x+40=0

x^2-(10+4)x+40=0

x^2-10x-4x+40=0

pick out the common one!

x(x-10)-4(x-10)=0

(x-10)(x-4)=0

now;

x-10=0

x=10(which is large x)

again:

x-4=0

x=4( which is small x)

Sasha and Frank both have toy cars. Sasha’s car goes 875 meters in 7 minutes. Frank’s car goes 1,232 meters in 11 minutes. Who’s car goes faster and how much faster?

Answers

Answer:

Sasha's car moves 13 meters faster than Frank's car

Step-by-step explanation:

I took Sasha's 875 meters and divided it by 7minutes and got 125

Then, I took Frank's 1232 meters and divided it by 11 minutes and got 112

Finally, I subtracted 125 by 112 and got 13 meters

Answer:

125 × 11 = 1375

1375 > 1232

Sashas car goes faster then Frank's

Sashas car goes 143 meters faster then Franks

A ferry boat heads across the river. Due to the current, the boat travels at an angle of 15 degrees north of west. If the boat traveled a total 178 yards, how far did it travel north and how far did it travel west?

Answers

46 yards was travelled north while 172 yards was travelled west.

Trigonometric ratios shows the relationship between the sides of a triangle and its angles.

For the question, the distance travelled north and distance travelled west can be determined using trigonometric ratio.

sin(15) = distance travelled north / 178

Distance travelled north = 46 yards

Also:

cos(15) = distance travelled west / 178

Distance travelled west = 172 yards

Hence, 46 yards was travelled north while 172 yards was travelled west.

first, make the line into slope-intercept form.

-3x - 5y = 1

-5y = 3x + 1

y = -3/5x - 1/5

a line parallell to this line has to have the same slope, so it could be but doesn't have to be y = -3/5x - 1

a line perpendicular to y = -3/5x - 1/5 has to have the opposite slope of it.

so, y = 5/3x +1

Answer:  163 dollars

======================================================

Explanation:

Let's add up the positive values only for now. So we get 172+48 = 220 which represents all the money coming into the account.

Do the same for the negative values. We'll simply add the positive versions of each (ignore the negative signs). So -17 and -40 can be thought of as 17 and 40, which add to 17+40 = 57. Ultimately this result is negative leading us to -57.

In other words, -17 + (-40) = -57

So you can see that adding negatives follows the same rule as positives. The only change is that everything turns negative.

The notation -57 means that 57 dollars is going out in terms of expenses, purchases, withdrawals, fees, etc.

---------------------

To summarize everything so far:

220 dollars in total is coming in57 dollars in total is going out

We subtract those results to find the final balance

balance = moneyIn - moneyOut = 220-57 = 163 dollars

We subtract positive versions of each number.

x = (-1 ±[tex]\sqrt{145}[/tex] )/8

Step-by-step explanation:

Quadratic formula: x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex] )/(2a)  

4x² + x - 9 = 0 ; General form of a quadratic is ax² +bx + c = 0

So a = 4, b = 1, and c = -9

x = -1 ±[tex]\sqrt{1^{2}-4(4)(-9)}[/tex] / 2(4)

x = -1 ± [tex]\sqrt{1 + 144}[/tex] /8

x = -1 ±[tex]\sqrt{145}[/tex] /8

x = (-1 + [tex]\sqrt{145}[/tex])/8    or x = (-1 - [tex]\sqrt{145}[/tex])/8
