Answer 1

Answer:

[tex](x^2+1)(x-3)(x+3)[/tex]

Step-by-step explanation:

x^2^2 - 9x^2 + 1x^2 - 9

= x^2(x^2 - 9) + 1(x^2 - 9)

= (x^2 + 1)(x^2 - 9)

= (x^2 + 1)(x-3)(x+3) <- (This is due to the a^2-b^2 theorem)

5n + 34 = -2 ( 1 - 7n)
this is due by midnight.

NO LINKS PLEASE!

Answers

Answer :

n = 4

Step-by-step explanation:

5n + 34 = -2(1-7n)

first distribute

5n + 34 = -2(1) -2(-7n)

5n + 34 = -2+14n

-5n

+2

then get all of n to the same side

36 = 9n

isolate the variable

36/9 = 9n/9

4 = n

Answer:

n=4

Step-by-step explanation:

Hi there!

We are given the following equation:

5n + 34 = -2(1-7n)

And we want to solve it for n

To do that, we want to isolate n (also written as 1n) on on side by itself.

In this equation, on the right side, we have -2(1-7n), which is in the way. We'll need to open it up.

In order to open up the parenthesis, we'll need to do the distributive property, where we will multiply -2 to both 1 and -7n, then add them together.

-2(1-7n)=-2+14n

That's for the right side.

The equation now looks like this:

5n + 34 = -2 + 14n

Remember that we will be trying to isolate n on one side

Subtract 5n from both sides to remove it from the left side:

5n + 34 = -2 + 14n

-5n                  -5n

__________________

34 = -2 + 9n

Add 2 to both sides to remove it from the right side:

34 = -2 + 9n

+2    +2

______________

36 = 9n

Now, we have numbers on one side and variables on the other, but we're not done yet, since remember; we want just n (or 1n), not 9n. We need to divide both sides by a number that will result in 1n

If we divide a number by itself, then the result is 1

So we should divide both sides by 9

4 = 1n, also written as 4=n , or n=4

Which equation helps to solve this problem?

Answers

Answer:

119+8h=271

Step-by-step explanation:

We already know she has read 119 pages out of 271. And we know the constant proportionality in this is 8 pages every hour. If we were able to find out how long it took for her, then we would add that with 119, because that, in total, will be 271/the whole book, with 152 pages of it in hours.

Find the measure of the missing angles.
26°

Answers

Answer:

y = 90

x = 64

Step-by-step explanation:

y is 90 because of right angle

if add 26 + 90 = 116 -> 180 (angle of straight line) - 116 = 64 which is angle of angle to left of y and therefore x bc opposite angles equal each other

or even if you saw the line that includes x, 26, and y, x is still 64

also, the other angle that is blank should be 26+y (if our calculations are correct) so it would be 116 -> and if we add up everything we should get 360 so, x/64 + 26 + y/90 + blank angle/64 + 116 = 360 -> all correct!

Answer:

The answer is 3 1/3

The value of the expression  −t/u+vw is 3 1/3 after pluggin the values of t, u, v, and w in the expression.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that,

The expression is:

= −t/u+vw

The values of t = 2, u=−2/3 , v=−1 , and w=−1/3

After pluggin the values of t, u, v, and w in the above expression we get:

= -2/(-2/3) + (-1)(-1/3)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

= 3 + 1/3

= 3 1/3 (in mixed fraction)

Thus, the value of the expression  −t/u+vw is 3 1/3 after pluggin the values of t, u, v, and w in the expression.

In the college class, there were 15 students that came to the review class before the test. This was 30% of the students in class. How many students were in the class, altogether?

Answers

Answer:

30 students

Step-by-step explanation:

The 15 students that came were 30% of the class:

30% = 15 students

To find 100%, we can first find 10% by dividing both sides by 3

10% = 3 students

(30% ÷ 3 = 10%, 15 ÷ 3 = 5)

Then, multiply both sides by 10 to get 100%

100% = 30 students

(10% × 10 = 100, 3 × 10 = 30)

Alex spends more time in his homework.

Step-by-step explanation:

To make it easier to compare their homework time on math, convert 2/5 into a percentage: Divide the numerator by the denominator:

Darius: 35%

Alex:  2/5 = 0.40 × 100 = 40%

Seeing both percentages make it easier to determine that Alex spends more time in his homework than Darius.

Answer:

Alex spends more time doing math homework. 2/5 is equal to 4/10 and 4/10 as a decimal is 0.4 which is 40%. 40% is greater than 35% so Alex spends more time than Darius doing math homework.

What is the smallest distance between the origin and a point on the graph of:y=1/sqrt(2)*(x^2-8)

Answers

What we are being asked here is to simply minimize distance. Also, note that we can write
f
(
x
)
=

x
as
y
=

x
.
Now, what is this "distance?" How do we find it? Well, if you think back to Algebra I or Geometry, you'll remember that the distance between two points
(
x
1
,
y
1
)
and
(
x

,
y

)
is given by:

(
y

y

Ok, so what is

and
(
x

in our example?
(
x

y

is simple - it's just the point given in the problem,
(
4
,
0
)
. Because we don't know what
x

is, we'll just call it
x
for now. As for
y
2
, we don't know that either; and since
y
=

x
, we'll call it

x
.
Our formula then becomes:

. Substituing

(the place where these two are closest) occurs at
