The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answ

bazaltina [42]

Answer:

The images of the question are missing, I found a matching question and image online, and it is in the attachments.

Answer:

The scale factor of the triangles from the left to the right is 2

The scale factor of the triangles from the right to the left is 1/2

Step-by-step explanation:

From the image, the right triangle on the left has the following dimensions:

Hypotenuse = 10

length of one side = 10

While the right triangle on the right has the following:

Hypotenuse = 20

Length of one side = 20

From the dimensions above it can be seen that the triangle on the right has a dimension of 2 times the triangle on the left:

Left (10) × 2 = right (20)

Therefore the scale factor of the triangles from the left to the right is 2

The scale factor of the triangles from the right to the left is 1/2

Can someone please help me! I don’t understand how to do this!

Answer:

a. 4x^2 +16x -48 = 4x^2 +16x -48

b. -3x^2 +12x +36 = -3x^2 +12x +36

c. x^2 +12x +35 = x^2 +12x +35

Step-by-step explanation:

In general, you would prove this by transforming one of the expressions into the other. The easiest would be to transform the factored form into the vertex form, perhaps, as this would spare you trying to explain the magic of factoring.

Alternatively, you can transform both expressions into the same (standard) form. I believe that will be the easiest of all.

The product of two binomials is ...

(x +a)(x +b) = x(x +b) +a(x +b) = x^2 +bx +ax +ab

(x +a)(x +b) = x^2 +(a+b)x +ab . . . . after collecting terms

The square of a binomial is the same thing, but with b=a, so ...

(x +a)^2 = x^2 +2a +a^2

Using these forms, we can avoid showing all of the intermediate "work" of making the desired transformations.

a. 4(x -2)(x +6) = 4(x +2)^2 -64

4(x^2 +4x -12) = 4(x^2 +4x +4) -64 . . . . . expanding the products

4x^2 +16x -48 = 4x^2 +16x +16 -64 . . . . using the distributive property

4x^2 +16x -48 = 4x^2 +16x -48 . . . . . collect terms; expressions are equal

b. -3(x +2)(x -6) = -3(x -2)^2 +48

-3(x^2 -4x -12) = -3(x^2 -4x +4) +48

-3x^2 +12x +36 = -3x^2 +12x -12 +48

-3x^2 +12x +36 = -3x^2 +12x +36

c. (x +5)(x +7) = (x +6)^2 -1

x^2 +12x +35 = x^2 +12x +36 -1

x^2 +12x +35 = x^2 +12x +35

Alexus [3.1K]

Answer:

$\frac{A}{1 + rt}$

Step-by-step explanation:

$a = p + prt$

Distributive property:

$A = P(1 + rt)$

The divide both sides by $( 1 + rt)$ :

$\frac{A}{1 + rt}$
