Factor the difference of squares.
x2 - 400
The factored form of x2 - 400 is
Answer:
The factored form of x²-400 is (x+20)(x-20).
Step-by-step explanation:
Given the expression
[tex]x^2\:-\:400[/tex]
As the square of 20 is 400. Therefore, rewrite 400 as 20²
⇒ [tex]x^2-20^2[/tex]
[tex]\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]
Thus, the expression becomes
[tex]x^2-20^2=\left(x+20\right)\left(x-20\right)[/tex]
Thus, the factored form of x²-400 is (x+20)(x-20).

Another car dealership sells a truck for the wholesale price of $12,000. During a special sales event, the dealership offers a 10% discount off of the price. After the discount, how much will a customer pay for this vehicle? Show your work.
Answer:
$10,800
Step-by-step explanation:
Given that:
Wholesale price of the truck = $12,000
At the special sales event, the discount offered on the price = 10% of the wholesale price
Therefore the discount can be calculated as follows:
10% of Wholesale price
Wholesale price is given as $12,000.
[tex]\Rightarrow \dfrac{10}{100} \times 12000\\\Rightarrow \bold{\$1200}[/tex]
Now, we have to find the price to be paid by customer after the discount being offered due to the special sales event.
Discounted price = Wholesale price - Discounted offered due to special sales event.
Discounted price = $12000 - $1200 = $10,800
Therefore, the answer is:
$10,800

Find the percent of change from 74 hours to 85 hours.
Answer:
The answer would be 14.8645, but it'd be repeating, so it's actually 14.864864864864865.
I think you should write the entire number down just in case.
I'm so sorry. It would be a percent increase, so it's a positive.

What are the factors of -24 that have a sum of 5?
Answer:
Step-by-step explanation:
5 Easy as 1-2-3
5 is a prime number.
Prime factorization: 5 is prime.
The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.
Factors of 5: 1, 5.
Factor pairs: 5 = 1 x 5.
5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.
In $\triangle PQR,$ the sum of $\angle P$ and $\angle Q$ is $60^\circ.$ What is the measure of $\angle R?$
Answer:
120
Step-by-step explanation:
We know that : m<P + m<Q= 60.
So, 180-60=120
Question 8 (5 points)
(02.07 MC)
In the figure shown, what is the measure of angle x? (5 points)
150 degrees
110 degrees
105 degrees
100 degrees
Given:
Consider the below figure attached with this question.
To find:
The value of x.
Solution:
According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.
In triangle ABC, using exterior angle theorem, we get
[tex]\angle ACD=\angle ABC+\angle BAC[/tex]
[tex]x=75^\circ +30^\circ [/tex]
[tex]x=105^\circ [/tex]
The value of x is 105 degrees.
Therefore, the correct option is C.

Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90°. The length of the longest side of the triangle is not known. How many different triangles can be drawn with these dimensions? Explain your reasoning.
Step-by-step explanation:
Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90.
If one of the angle is 90 degrees, it would mean that he has drawn a right angle triangle.
Hypotenuse is the longest side of the triangle. We can find it using Pythagoras theorem as follows:
[tex]h=\sqrt{5^{2}+12^{2}}\\\\=13[/tex]
The longest side is 13 cm.
If we keep the longest side the same and if two sides i.e. 5 cm and 12 cm are replaced, a new triangle can form.

Write the equation of the line passing through the points (28,4) and (-4,-4).
Answer:
The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

Dasher wrapped 16 of the 54 presents for Christmas.
Please represent how many presents his contribution was as a fraction and as a percent.
9/27 and 30%
Step-by-step explanation:
16/ 54 then reduced to 9/27
to find percent divide 16/54 to get 0.296 then round that to 0.30 multiple by 100 to change to percent which is also just moving decimal over 2 places so 30%

Which facts could be applied to simplify this expression? Check all that apply.
5 x + 3 y + (negative x) + 6 z
Answer:
The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.
C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.
D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

[tex]\huge\boxed{\sf \frac{-16}{147} }[/tex]
Step-by-step explanation:
Multiplicative Inverse of [tex]\sf 3\frac{1}{2} (\frac{7}{2} )[/tex] = [tex]\sf \frac{2}{7}[/tex]
Multiplicative inverse of any number is the reciprocal of that number.
Additive inverse of [tex]\sf 2\frac{5}{8}(\frac{21}{8} )[/tex] = [tex]\sf -\frac{21}{8}[/tex]
Additive Inverse of any number is the number that has the opposite sign.
Solution:
[tex]\sf \frac{2}{7} / - \frac{21}{8} \\\\\frac{2}{7} * - \frac{8}{21} \\\\= \frac{2*(-8)}{7*21} \\\\= \frac{-16}{147} \\\\\rule[225]{225}{2}[/tex]
