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).

The expression 8x + 2(3y) represents the total amount, in dollars, that Davellyn spent on tank tops and scarves, where x represents the number of tank tops she bought and y represents the number of scarves she bought. Which statement must be true about the amount Davellyn spent?
She spent 8x dollars on scarves.
She spent 8 dollars for each scarf.
She spent 6y dollars on scarves.
She spent a total of 14 dollars.
Answer:
She spend 6y dollars on scarves.
Step-by-step explanation:
The question states that y represents the number of scarves she bought, so the first and second statements would be incorrect. You don't know how much she spent in total, so the fourth statement would also be wrong. So it's the third statement.
Also, you can just do 2*(3y), which is 6y.
Answer:
The answer is C

[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]

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.
Which of the following are valid names for the given triangle? Check all that
apply.
A. AXM
B. XMA
C. TAY
D. AXT
E TAX
F.XTA
There are three valid names for the given triangle AXT, TAX, and XTA.
A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same. In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides. Every triangle is bicentric and convex. The triangle's interior is the area of the plane it encloses; the outside is the rest of the plane. Triangle geometry, as the study of triangles is frequently referred to, is a rich field of geometry that is full of stunning outcomes and surprising connections. Let S stand for a side of a triangle and A for an angle. Then, let a group of Ss and As be concatenated so that adjacent letters stand for adjacent sides of a triangle and adjacent angles. According to the SSS theorem, a triangle can only exist if it has three sides, two angles, and a side, or two sides and an adjacent angle (SAS theorem). The three unknown quantities (there are a total of three sides and three angles) can be uniquely identified in each of these situations. Other side and angle combinations do not necessarily result in a triangle being formed: the AAA theorem states that three angles specify a triangle but only up to certain scale size and that one angle and two sides without it may describe one, two, or no triangles.

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.
