Amaya is asked to find the side lengths of the triangle
shown below. What is her error?
Answers
Answer:
Her error was that she equated 2x to 6 instead of equating 2x to 3x-5
Step-by-step explanation:
Find the diagram of the question attached.
According to the triangle given, you can see that the base angles are equal. This shows that the triangle is an isosceles triangle. If the base angles are the same, this means that the length of the slant sides are also equal i.e
2x = 3x-5
Get x first;
2x = 3x-5
2x - 3x = -5
-x = -5
x = 5
Get the side length
For side length 2x, the length is 2(5) = 10
For side length 3x-5, the length is 3(5) - 5 = 10.
Hence the length of the sides is 10
Amaya is wrong because she equated the wrong sides. She equated 2x to 6 instead of equating 2x to 3x-5 as shown in the calculation above.

Since Gordon gets 11 more sweets than Sushil, then
4x = 3x + 11 ( subtract 3x from both sides )
x = 11
Thus
total sweets = 4x + 4x + 3x = 11x = 11(11) = 121

x2 - 400
The factored form of x2 - 400 is
Answers
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).

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 distance between 2 cities is 145 miles . A truck can cover this distance in 2.5 hours. A car is a.5 times as fast as the moving truck. How long does it take to meet, if they start moving simotanously
Answers
Answer:
25 minutes
Step-by-step explanation:
Given that:
Distance between 2 cities = 145 miles
Time taken by truck = 2. 5 hours
Speed of car = 5 times the speed of truck
Speed of truck = distance / time
Speed of truck = 145 / 2.5
Speed of truck = 58 mph
Speed of car = 5 * 58 = 290 miles per hour
Time it takes to meet :
Time taken = distance / combined speed
Time taken = 145 / (290 + 58)
Time taken = 145 / 348
Time taken = 0.4166666 hours
Time taken = 0.4166666 * 60 = 25 minutes

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.
Answers
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.
