BRAINILEST!!!Mikel is determining if the two triangles below could be similar based on their side lengths.

dybincka [34]

ANSWER

statements accurately describe the triangles

The triangles could not be similar.

The ratios of the side lengths are not consistent.

Reason

As shown in the diagram the sides of the triangle are given

Similarity property on the sides length of the triangle

The corresponding sides of the two triangles are proportional the triangles must be similar.

$\frac{WX}{RT} = \frac{18.0}{8.0}$

= 2.25

$\frac{WU}{TS} = \frac{15.0}{6.0}$

=2.5

$\frac{UX}{RS} = \frac{7.5}{3.0}$

=2.5

Thus by above we get

The ratios of the side lengths are not consistent.

thus triangles could not be similar.

Hence proved

Which expressions are equivalent to (2^2-9) (x + 3)?

mestny [16]

Answer:

$(x^2-3^2)(x+3)$

$(x-3)(x+3)(x+3)$

$(x-3)(x+3)^2$

Step-by-step explanation:

Given

$(x^2-9)(x+3)$

Required

Select 3 equivalent expressions

$(x^2-9)(x+3)$

Express 9 as 3^2

$(x^2-3^2)(x+3)$ --- This is one equivalent expression

Take $x^2 - 3^2$ as difference of two squares

$(x-3)(x+3)(x+3)$ -- This is another equivalent expression:

Solving further:

$(x-3)(x+3)(x+3)$ becomes

$(x-3)(x+3)^2$ -- This is another equivalent expression:

Hence, the equivalent expressions are:

$(x^2-3^2)(x+3)$

$(x-3)(x+3)(x+3)$

$(x-3)(x+3)^2$

If a 45º-45º-90º triangle has a hypotenuse of length 9, find the leg length.

iVinArrow [24]

Answer:

Step-by-step explanation:

x²+x²=9²

2x²=81

x²=81/2=(81×2)/4

x=9√2/2≈4.5√2≈6.36

x²+x²=11²

2x²=11²

x²=11²/2

x=11/√2=11√2/2≈7.78

John’s Bar is 60 km away from Ben’s Bar. Doug’s Bar is 40 km away from Kieran’s Bar. John’s Bar is 10 km nearer to Doug’s Bar th

soldier1979 [14.2K]

If we let x be the distance from John's Bar to Doug's bar then we can derive the expression,
(x - 10) + x = 40
The value of x from the equation is 25. This means that the distance between John's bar and Dough's bar is 15 km. Since, John's bar and Ben's bar are 60 km apart, the distance between Doug's bar and Ben's bar is 45 km.

What is 12, 4, -2, 0, 9, -2, 1, 7, 8, 2 in order from least to greatest

7nadin3 [17]

Answer:

-2 , -2 , 0 , 1 , 2 , 4 , 7 , 8 , 9 , 12

Step-by-step explanation:

Order each number from least to greatest. Note that if the number is numerically larger and attached is a negative sign (-), then it is towards the least. If it does not have a negative sign, it leans towards the most.

Your answer:

-2 , -2 , 0 , 1 , 2 , 4 , 7 , 8 , 9 , 12
