Answer:

Scale Factor states that the ratio that you get when you divide corresponding side lengths of similar figures.

Given: Triangle ABC is congruent to Triangle DEF.

Similar figures have corresponding angles that are equal and corresponding sides that are equal.

To find the scale factor,

you need to find the ratio between the corresponding sides of the triangle.

now, you can multiply each side of one triangle by the same number to get the sides of the other triangle.

∴ The number is the scale factor, that is what we are trying to find.

Answer:

Step-by-step explanation:

2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A

<em>used distributive property</em>

2(2x + 1) = 2(1 + 2x) → B

<em>used commutative property</em>

2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D

2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E

joja [24]

Answer:

BD = 9

Step-by-step explanation:

Since, the points B, C D and E all lie on the same line segment, in that order, such that the

ratio of BC:CD: DE is equal to 1:2:2. If BE = 15

Let BC = x, CD = 2x, DE = 2x

$\because BC+CD+ DE= BE\\\\\therefore x + 2x + 2x = 15..(\because BE =15)\\\\\therefore 5x = 15\\\\\therefore x = \frac{15}{5}\\\\\therefore x = 3\\\\\because BD = BC + CD\\\|\therefore BD = x + 2x \\\\\therefore BD = 3x\\\\\therefore BD = 3\times 3\\\\\huge \orange {\boxed {\therefore BD = 9}}$

1/3(12+X)=-8(6+X)<br> Find x

TEA [102]

If you would like to solve the equation 1/3 * (12 + X) = -8 * (6 + X) for X, you can calculate this using the following steps:

1/3 * (12 + X) = -8 * (6 + X)
1/3 * 12 + 1/3 * X = -8 * 6 - 8 * X
4 + 1/3 * X = - 48 - 8 * X
1/3 * X + 8 * X = - 48 - 4
8 1/3 * X = - 52
25/3 * X = - 52 /*3/25
X = - 52 * 3 / 25
X = - 156/25
X = - 6 6/25

The correct result would be - 6 6/25.
