Solve the equation for x.
x2 = 36
The solutions to the equation are
and
x2=36
We move all terms to the left:
x2-(36)=0
We add all the numbers together, and all the variables
x^2-36=0
a = 1; b = 0; c = -36;
Δ = b2-4ac
Δ = 02-4·1·(-36)
Δ = 144
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ‾‾√=144‾‾‾‾√=12
x1=−b−Δ√2a=−(0)−122∗1=−122=−6
x2=−b+Δ√2a=−(0)+122∗1=122=6

Answer:
x = -6 or +6
Step-by-step explanation:
You know from your multiplication tables that 6×6 = 36, so one answer is ...
x = 6
You also know that the product of two negative numbers is positive, so another answer is ...
x = -6
__
Check
x² = 6² = 6×6 = 36
x² = (-6)² = (-6)×(-6) = 36
_____
Alternate approach
If you like, you can rewrite the equation as ...
x² -36 = 0
This can be factored to ...
(x -6)(x +6) = 0
The zero product rule tells you this product will only be zero if one or the other factors is zero.
x -6 = 0 ⇒ x = 6
x +6 = 0 ⇒ x = -6
The two solutions are x = ±6.

a standard toilet uses 1.6 gallons per flush. If a toilet is flushed four times per day, how much water will be used in a month(30days)?
Answer:
192 gallons
Step-by-step explanation:
1.6 gallons x by 4 (the amount of times flushed in a day) = 6.4 gallons a day
6.4x30 (days in a month) = 192
192 gallons of water is being flushed a month
Answer:
192 gallons

Step-by-step explanation:
Rashid owned n sheep. Eifion had exactly 4 times as many sheep as Rashid. Rashid buys 17 extra sheep. Eifion sells 8 of his sheep. Eifion still has more sheep than Rashid. Form an inequality, in terms of . Solve the inequality to find the least value of
4n - 8 > n + 17
n > 8.33
This means n is greater than 8.33.
We can have 9, 10, 11, 12, 13, ,,, and so on.
The least value is 9.
The least value of the number of sheep is 9.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Rashid:
Number of sheep owned = n
Bought 17 sheep = n + 17
Eifion:
Number of sheep owned = 4n
Sells 8 sheep = 4n - 8
Eifion still has more sheep than Rashid.
This means,
4n - 8 > n + 17 ______(1)
Solving for n in (1).
4n - 8 > n + 17
Subtract n on both sides.
4n - 8 - n > n + 17 - n
3n - 8 > 17
Add 8 on both sides.
3n - 8 + 8 > 17 + 8
3n > 25
Divide 3 on both sides,
n > 25/3
n > 8.33
This means n is greater than 8.33.
We can have 9, 10, 11, 12, 13, ,,, and so on.
The least value is 9.
Thus,
The least value of the number of sheep is 9.

time=2hours
speed=299/2
speed=149.5km/h
Answer: 149.5 km/h or 92.58 mph
Step-by-step explanation:
Divide 299/2 to get the Kilometers Per Hour= 149.5

Answer:
Well, for triangle rectangles, we have the relations:
Cos(A) = (adjacent cathetus)/(hypotenuse)
Sin(A) = (opposite cathetus)/(hypotenuse)
Tan(A) = (opposite cathetus)/(adjacent cathetus)
Where the adjacent cathetus is the cathetus that is adjacent to the angle, the opposite cathetus is the one that is opposite to the angle, and the hypotenuse is the side that is opposite to the 90° angle.
Here we want to solve 3 to 9.
3) We want to find values sin(D) and sin(E) in that triangle.
Remember the above relationship for the sin function, here will have:
sin(D) = 12/15 = 0.8
sin(E) = 9/15 = 0.6
4)
Sin(E) = 12/37 = 0.3243
Sin(D) = 35/37 = 0.9459
5)
Sin(E) = 45/53 = 0.8491
Sin(D) = 28/53 = 0.5283
6)
Remember that: Sin(A) = (opposite cathetus)/(hypotenuse)
In the image, 5 is the adjacent cathetus to the angle A, and the opposite cathetus to angle A is the one in front of it, 12, then the equation should be:
Sin(A) = 12/13
Now we should use the cosine relationship:
Cos(A) = (adjacent cathetus)/(hypotenuse)
7)
Cos(X) = 27/45 = 0.6
Cos(Y) = 36/45 = 0.8
8)
Cos(X) = 15/17 = 0.824
Cos(Y) = 8/17 = 0.4706
9)
Cos(X) = 13/26 = 0.5
Cos(Y) = (13*√3)/26 = 0.866
find missing factor 7^-5 = blank × 7^6
Answer:
7^-11
Step-by-step explanation:
Given the expression 7^-5 = blank × 7^6
Let the blank be x
7^-5 = x × 7^6
x = 7^-5/7^6
According to law of indices a^b/a^c = a^b-c
x = 7^(-5-6)
x = 7^-11
Hence the missing factor is 7^-11

This is a question for geometry and its pretty hard.
Answer:
m EAD = 56
m EDA = 35
x = 4
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other. This means that AE and EC are equal. To find x, simply set 2x + 3 = 11, and solve.
2x + 3 = 11
2x = 8
x = 4
Additionally, since the sides of a parallelogram are parallel, BC + AD are parallel, as are AB + DC. This make ECB + EAD and EBC + EDA opposite interior angles (have same measure). Thus, since we know ECB = 56 and EBC = 35, EAD also = 65 and EAD also = 35

In your own words, explain the process of how you would divide 2/3 by 1/2
Answer:
Down below :) Hope this helps!
Step-by-step explanation:
To divide fractions, you have to flip the second fraction.
For example, 2/3 divided by 1/2 is the same thing as 2/3 x 2/1, you have to flip the second fraction. When you do this, your answer will be 4/3 or 1 1/3.

Divide 200kg in the ratio 15:9:1
Answer:
120kg, 72kg and 8kg
Step-by-step explanation:
Given the ratios 15:9:1
total ratio = 15+9+1 = 25
For the ratio of 15
Share = 15/25 * 200
Share = 3000/25
Share = 120kg
For the ratio of 9
Share = 9/25 * 200
Share = 1800/25
Share = 72kg
For the ratio of 1
Share = 1/25 * 200
Share = 200/25
Share = 8kg

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor's office, her brother's actual height is 4 feet, 2 inches. Should Clare's or the doctor's measurement be considered the actual height?
Answer: The Doctor's.
Step-by-step explanation:
Claire's estimate was simply that, an estimate. The doctor's measurement on the other hand is the actual height of her brother because he actually got measured.
This means that the doctor's measurement is more accurate and would make more sense to be used.

Whatis the answer to the problem
Answer:
slope = [tex]-\frac{1}{8}[/tex]
Step-by-step explanation:
Use the slope formula given in the question to solve for the slope. The [tex]m[/tex] is the variable representing the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] values are x and y values of one point. The [tex]x_2[/tex] and [tex]y_2[/tex] are x and y values of another point.
So, use the x and y values of the points given and substitute them in the correct order into the formula:
[tex]m = \frac{(7)-(9)}{(10)-(-6)}\\m = \frac{7-9}{10+6} \\m = \frac{-2}{16} \\m = -\frac{1}{8}[/tex]
Thus, the slope is [tex]-\frac{1}{8}[/tex].
