x = - 7

To get rid of the square root. Isolate the square root and it's multiple. Then square both sides to get rid of it. Don't forget to square the multiple, in this case - 2 becomes 4. Solve for x like you normally do.

Answer:

10.5 yards after 15 years

Step-by-step explanation:

2.1 feet times 15 years, which equals to 31.5 feet, convert 31.5 feet into yards, so divide it by 0.3, and that equals to approximately 10.5 yards

Answer:

Length 18 yds, Width 9 yds

Step-by-step explanation:

2x + 2x + x + x = 54

Divide both sides by 6

x = 9

Plug 9 into equation above

2(9) + 2(9) + 9 + 9 =

18 + 18 + 18 = 54

Answer:

Step-by-step explanation:

if you need an answer I would be 112 given the information in the question,

but there seems to be something wrong (probably my interpretation) ..

here  is the logic (and why there is an issue) ....

Assuming that every "movement" is "5 forward, then 3 back"

we can assume that every movement takes 8 steps ...

given this one would assume that the total steps has to be a multiple of 8 (but it is not)

460/8 is 57.5 ....

let us assume that came out even... every movement has five forward and three back a net result of 2 forward... if the is repeated 57.5 time the result would be 112 steps forward

it is the 57.5 that does not seem correct

1 square meter is equivalent to 0.0001 square centimeter

72.576 cubic inches. in cubic feet is 0.042 cubic feet

Conversion in math is a way of changing the value of an expression using units.

1) In order to change 1 square meter to square centimeters, we will use the conversion

1m = 0.01cm

Taking the square of both sides

(1m)² = (0.01cm)²

1m² = 0.01cm * 0.01cm

1m² = 0.0001cm²

This shows that 1 square meter is equivalent to 0.0001 square centimeter

2) We are to convert 72.576 cubic inches to cubic feet. Using the conversion factor:

1 cubic inch = 0.000578704 cubic feet

72.576 cubic inches = x

Cross multiply

x = 72.576 * 0.000578704

x = 0.042 cubic feet

This shows that 72.576 cubic inches. in cubic feet is 0.042 cubic feet

Answer:

1/6?

Let's do it...

( (3^(3/4))/(3^(3/8)) )^4/9

According to indices rules here the denominator and numerator has the same base and they are dividing so the powers will subtract..... Its just a formulae not rocket science so don't freak out.

So ( 3^(3/4 - 3/8)) ^4/9

= ( 3^(3/8)) ^4/9

Again with indices rule the powers will multiply

Which will return us 3^1/6 which corresponds 3^x..... Hence x =1/6

Answer:

x2 + 8

Step-by-step explanation:

The value of the composite function (f - g)(x) is x² + 8.

The correct option is D.

Any function that is created by combining two or more other functions is referred to as a composite function. To put it another way, given two functions, f, and g, the composite function of f and g, denoted as f(g(x)), is a new function that applies g to the input x before applying f to the output of g (x).

Given:

f(x) = 2x² + 1 and g(x) = x² - 7.

To find (f – g)(x), we need to subtract g(x) from f(x):

(f - g)(x) = f(x) - g(x)

where f(x) = 2x² + 1 and g(x) = x² - 7.

Substituting these expressions into the equation, we get:

(f - g)(x) = (2x² + 1) - (x² - 7)

Simplifying the expression on the right-hand side by distributing the negative sign, we get:

(f - g)(x) = 2x² + 1 - x² - 7)

Combining like terms, we get:

(f - g)(x) = x² + 8.

Therefore, (f - g)(x) = x² + 8.

Answer:

3a + 2b + 4c = D

D = Amount Spent

Step-by-step explanation:

For any two points that we have, we can find a line that passes through them, so the first part is true, only two points are needed to determine a line.

Then you say:

"why are three ordered pair solutions or points found for a linear equation"

A linear equation is something of the form:

y = a*x + b

Where we assume that you know a and b.

Given that case, we can see that we have infinite solutions.

Suppose that you want to solve this for y, then for each possible value of x you will have a different solution, and you can have infinite values of x there, so there are infinite solutions.

Now, what I think you are asking is:

Why we should use 3 points to check if a relation is linear or not?

Well, exactly for the first thing you said. We always can find a line that passes through two given points, but that is not the case for 3 given points.

So, if in a given relation we use 3 points, and we can see that these are collinear, then we can conclude that the relationship gives a linear equation (ideally you could use more than 3 points, but usually is enough)

Number of cups are 32.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A dietitian prepares a high-protein drink for 24 residents.

And, Each drink measures 3/4 cup.

Let number of cups of the drink will she prepare = x

So, We get;

⇒ 3/4 × x = 24

⇒ x = 24 × 4 / 3

⇒ x = 32 cups

Thus, There are 32 total cups of the drink will she prepare.

The value of the arithmetic series is 550. The correct answer is C) 550.

To evaluate the arithmetic series, we can use the formula:

Sn = (n/2)(2a1 + (n-1)d)

Given:

a1 = 10 (first term)

d = 8 (common difference)

n = 11 (number of terms)

Plugging the values into the formula:

Sn = (11/2)(2(10) + (11-1)(8))

= (11/2)(20 + 10(8))

= (11/2)(20 + 80)

= (11/2)(100)

= 550

Therefore, the value of the arithmetic series is 550.

The correct answer is C) 550.
