Very easy!! help!! urgent!! its on ratio
masha68 [24]

Answer:

A and B are correct

Step-by-step explanation:

if x:y is 1:3 then x is 1 and y is 3

1/3 of 3 is 1 so A is correct

3/4(1+3) is 3 so B is correct

But

1/4 × 3 is not 1 so C is not correct

3/4 ×1 is not 3 so D isn't correct

Choose the congruence theorem that you would use to prove the triangles congruent.
Elena L [17]

<u><em>Answer:</em></u>

SAS

<u><em>Explanation:</em></u>

<u>Before solving the problem, let's define each of the given theorems:</u>

<u>1- SSS (side-side-side):</u> This theorem is valid when the three sides of the first triangle are congruent to the corresponding three sides in the second triangle

<u>2- SAS (side-angle-side):</u> This theorem is valid when two sides and the included angle between them in the first triangle are congruent to the corresponding two sides and the included angle between them in the second triangle

<u>3- ASA (angle-side-angle):</u> This theorem is valid when two angles and the included side between them in the first triangle are congruent to the corresponding two angles and the included side between them in the second triangle

<u>4- AAS (angle-angle-side):</u> This theorem is valid when two angles and a side that is not included between them in the first triangle are congruent to the corresponding two angles and a side that is not included between them in the second triangle

<u>Now, let's check the given triangles:</u>

We can note that the two sides and the included angle between them in the first triangle are congruent to the corresponding two sides and the included angle between them in the second triangle

This means that the two triangles are congruent by <u>SAS</u> theorem

Hope this helps :)

                          0
The answer is C.

2. A. 9x² + 12x - 3
        3(x²) + 3(4x) - 3(1)
        3(x² + 4x - 1)

    B. 9x² + 3x - 5
        Not Factored

    C. 6x² + 10x - 4
        2(3x²) + 2(5x) - 2(2)
        2(3x² + 5x - 2)
        2(3x² + 6x - x - 2)
        2(3x(x) + 3x(2) - 1(x) - 1(2))
        2(3x(x + 2) - 1(x + 2))
        2(3x - 1)(x + 2)

    D. 6x² + 7x - 6

Graph the image of this figure after a dilation with a scale factor of 2 centered at the origin.
den301095 [7]

Answer:  

Here, the coordinates of the given rectangle are (1,2), (3,2), (1,-1) and (3,-1)

In the dilation by the scale factor k with centered at origin,

(x,y)\rightarrow (kx,ky)

Thus, If the dilation occurs by the scale factor of 2 with centered at origin,

New coordinates of the Rectangle are,

(1,2)\rightarrow (2\times 1, 2\times 2)

(3,2)\rightarrow (2\times 3, 2\times 2)

(1,-1)\rightarrow (2\times 1, 2\times -1)

(3,-1)\rightarrow (2\times 3, 2\times -1)

Thus, the coordinates of new rectangle are,

(2,4), (6,4), (2,-2) and (6,-2)
