Answer:

C. [tex]\sqrt{3x^2+21x}[/tex]

Step-by-step explanation:

When one multiplies two radicles, one multiplies each term in the radical by the term in the other radical, then one simplifies the result and puts the radical sign over the result. If there are any perfect squares one will take the terms out. In this scenario, such is not the case.

[tex]\sqrt{3x}*\sqrt{x+7}\\\\\sqrt{3x(x+7)}\\\\\sqrt{3x^2+21x}[/tex]

Answer:

a) the new perimeter is 2 times the old perimeter

b) the new area is 4 times the old area

Step-by-step explanation:

b) the doubling of the length and width affects the area formula like this:

old triangle area formula = 1/2bh

new triangle area formula = 1/2(2b)(2h),   you see the 2 x 2 causes the area to be 4 fold

Answer:

Your answer is 27

I hope I helped, would appreciate brainliest! ;)

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

27% = 27 'out of one hundred',

p% is read p 'percent',

27% = 27/100 = 27 ÷ 100

Calculate percentage:

'Percentage' is obtained by multiplying 100 by 27%

27% of 100 is equivalent to multiplying them:

27% × 100 = ?

27% × 100 =

(27 ÷ 100) × 100 =

(27 × 100) ÷ 100 =

2,700 ÷ 100 =

27

Proof.

How do we check the result?

If 27% × 100 = 27 =>

Divide 27 by 100...

... And see if we get as a result: 27%

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

n/100 = n%, any number.

Calculate the percent value:

27 ÷ 100 =

0.27 =

0.27 × 100/100 =

(0.27 × 100)/100 =

27/100 =

27%

So we have proved that the calculations are correct.

Answer:

1 and 3

Step-by-step explanation:

it is where the graph meets the x axis line

Answer:

increase

Step-by-step explanation:

Increase definition: become or make greater in size, amount, intensity, or degree.

Decrease definition: make or become smaller or fewer in size, amount, intensity, or degree.

Given:

The expression is

[tex]2\times 2\times 2\times 2\times 2[/tex]

To find:

The index notation of the given expression.

Solution:

Index: The power of a number and a variable is called its index.

Index notation: The expression which has a base and a power.

In the given expression 2 is multiplied 5 times, so by using the property of exponent we get

[tex]2\times 2\times 2\times 2\times 2=2^{1+1+1+1+1}[/tex]       [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]2\times 2\times 2\times 2\times 2=2^{5}[/tex]

Therefore, the index notation of the given expression is [tex]2^5[/tex].

Answer:

1 ) 140

2) 60

Step-by-step explanation:

1. It touches the y intercept at 140 and 0 in the x axis so 140

NOTE : THE NUMBER THE TOUCHES THE Y INTERCCEPT IS ALWAYS THE ANSWER/ IT GOES DOWN 3 ACROSS 3 SO IT AND U WILL SEE IF IT TOUCHES THE Y INTERCEPT IT WILL BE 140

2. it goes from 140 to 200 just subtract them to get how much she gets

Answer:

C.

Step-by-step explanation:

14/3 = 4.66

/2/=2.33

-14/4 = -3.5

So the numbers are 4.66, 4.3, 2.33, 1.3, -2 and -3.5

So the numbers are -14/4, -2, 1.3,/2/, 4.3, 14/3

Answer:

Slope = -3, Y-intercept = -2, y = -3x -2

Step-by-step explanation:

There are multiple points plotted on the graph, but right now, we only need to focus on two.

(-2, 4) (-1, 1)

Using the ordered pairs, do delta y/ delta x to get the slope

(1-4)/(-1-(-2)

(-3)/(-1+2)

(-3)/(1)

Slope = -3

y = -3x + b

As shown on the graph, the y-intercept is -2. It is when x = 0

So, for the equation, substitute the found values.

y = -3x -2

Answer:

The number could be [tex]-7.5[/tex] or [tex]8[/tex].

Step-by-step explanation:

I'm going to assume this means "The square of a number is 60 greater than half of the number." Let the number be [tex]x[/tex]. The square of [tex]x[/tex] will be [tex]x^{2}[/tex]. "is" denotes that we use the "[tex]=[/tex]" sign, so our equation so far is [tex]x^{2} =[/tex] . Half of [tex]x[/tex] is [tex]\frac{1}{2}x[/tex], and "greater than" implies addition, so [tex]60[/tex] greater than [tex]\frac{1}{2}x[/tex] is [tex]\frac{1}{2}x+60[/tex]. Therefore, the equation is [tex]x^{2} =\frac{1}{2}x+60[/tex].

Solving for [tex]x[/tex], we get:

[tex]x^{2} =\frac{1}{2}x+60[/tex]

[tex]2x^{2} =x+120[/tex] (Multiply both sides of the equation by [tex]2[/tex] to get rid of the fraction)

[tex]2x^{2} -x-120=0[/tex] (Subtract [tex]x+120[/tex] from both sides of the equation to make it easier to solve)

[tex]2x^{2} +15x-16x-120=0[/tex] (Split [tex]-x[/tex] into [tex]15x-16x[/tex] to make the LHS easier to factor)

[tex]x(2x+15)-8(2x+15)=0[/tex] (Take a common factor out of the first two terms and the last two terms)

[tex](2x+15)(x-8)=0[/tex] (Take another common factor out)

[tex]2x+15=0,x-8=0[/tex] (Zero Product Property)

[tex]x=-7.5,8[/tex] (Solve)

Answer:

x=128

Step-by-step explanation:

180-52=128

Answer: x= 128 degrees

Step-by-step explanation:

Angle “x” and angle with measure of 52 degrees are a linear pair.

Linear pairs sum to 180.

52+x=180. Subtract 52 from both sides.

X= 128

*OR you can use angles around a point sum to 360 degrees.

52+38+142+x = 360. Combine like terms.

232+x= 360. Subtract 232 from both sides.

X= 128
