The measure of ab and df are 3cm and 7.5cm respectively

<h3 /><h3>Similarity theorem of shapes</h3>

In order to determine the missing sides, we need to take the ratio of the similar sides as shown:

1) ab/de = ac/df

ab/de = ab+bc/df

Substitute the given values

ab/2 = ab+4.5/2+3

ab/2 = ab+4.5/5

2(ab+4.5) = 5ab
2ab+9=5ab

3ab = 9

ab = 3cm

Hence the measure of ab is 3cm

2) ae/ce = bf/df

24/9 = 20/df

24df =. 9(20)

24df = 180

df = 7.5cm

Hence the measure of ab and df are 3cm and 7.5cm respectively

Answer:

Step-by-step explanation:

1)

A. 2 meters to centimeters

1 m = 100 cm

2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2

B)108 centimeters to meters

100 cm =1 m

1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m

C)2.49 meters to centimeters

1 m = 100 cm

2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm

D)50 centimeters to meters

100 cm = 1m

1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m

E)6.3 meters to centimeters

1 m = 100 cm

6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630  cm

F)7 centimeters to meters

100 cm = 1 m

1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m

2)

a)4 meters to millimeters

1 m = 1000 mm

4 m = 4000 = 4 \times 10^3 mm

b)1.7 meters to millimeters

1 m = 1000 mm

1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm

5u^2 + 6 = -13u please help
Komok [63]

Answer:

u = -2, -3/5

General Formulas and Concepts:

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Factoring
  • Finding roots

Step-by-step explanation:

<u>Step 1: Define equation</u>

5u² + 6 = -13u

<u>Step 2: Solve for </u><em><u>u</u></em>

  1. Rewrite:                    5u² + 13u + 6 = 0
  2. Factor:                      (u + 2)(5u + 3) = 0
  3. Find roots:                u = -2, -3/5

Consider the function f (x) = x2.
klio [65]

Answer: The graph is shifted 2 units to the right.

Step-by-step explanation:

Given a function f(x), we know that one transformation rule is:

If f(x-k) then the function is shifted "k" units to the right.

 Therefore, for the function f(x)=x^{2}, when we subtract 2 from the input, then we get the function g(x) in the form:

 g(x)=(x-2)^{2}

We can conclude that subtracting 2 from the input of the function f(x)=x^{2}, then the graph is shifted 2 units to the right.
