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!
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
Hope this helps!
50 people purchase item 5(the item 5 cost $18.94) seven of these customers use a coupon for 15% off. how much money do you make off the sales of item 5?

Marie is reading a 271-page book. She has already read 119 pages. If she reads
at about 8 pages per hour, how long will it take her to finish the book?
Which equation helps to solve this problem?
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°
yº
x°
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!

Evaluate the expression −t/u+vw , where t = 2, u=−2/3 , v=−1 , and w=−1/3 .3 1/31 2/3−2 2/3
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.

Tamir and his little sister are saving up money to buy a joint birthday present for their
mother. Tamir already has $11 saved and plans to save $15 per week from his allowance. His
sister has $19 saved so far and will save $7 per week from hers. The two siblings will soon
have saved the same amount towards their mother's gift. How much will each one have
saved? How long will that take?
Tamir and his sister will each have saved $
in
weeks.
Answer:
X = 1 week
Each will have $ 26 in 1 week
Step-by-step explanation:
Tamar: y = 15x + 11
Sister: y = 7x + 19
15x + 11 = 7x + 19
15x - 7x = 19 - 11
8x = 8
x = 8/8
15(1) + 11 = 26

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?
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)

Answer:
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.

Leslie drank 51 ounces of water in 6 hours. At this rate, how much water did Leslie drink in one hour?
Answer:
She drank 10.67 oz in one hour.
Step-by-step explanation:
You would multiply the total oz of water drank by the hours.
51 ÷ 6 = 10.6666...
Then you would round it up to 10.67.
Answer:
The correct answer is 8.5 ounces in the matter of one hour
Step-by-step explanation:
To get this answer you will need to use division.
Divide 51 with 651 divided by 6 will be 8.5 as a decimal
Therefore the correct answer is 8.5In which was being drank in the matter of one hour
