1. (16x² + 48x) ÷ 8x

$\implies \sf{\dfrac{8x(2x + 6)}{8x}}$

$\implies \sf{2x + 6}$

2. (56x² - 14x) ÷ 7x

$\implies \sf{\dfrac{7x(8x - 2)}{7x}}$

$\implies \sf{8x - 2}$

3. (20x² - 32x) ÷ 4x

$\implies \sf{\dfrac{4x(5x - 8)}{4x}}$

$\implies \sf{5x - 8}$

4. (18x² + 15x) ÷ 3x

$\implies \sf{\dfrac{3x(6x + 5)}{3x}}$

$\implies \sf{6x + 5}$

If ORBIT is coded BEOVG, then how is PLANET coded? /

arlik [135]

Answer:

1. CYNARG

Step-by-step explanation:

This a example of Caesar's Cipher, in which each letter in the original word leads to a ciphered letter according to the following equation:

$C = (P + o) \text{mod} 26$

In which C is the index of the Ciphered letter in the alphabet, P is the index of the original letter and o is the offset.

Finding the offset:

O is coded B

O is the 15th letter in the alphabet, so $P = 15$ .

B is the 2nd letter in the alphabet, so $C = 2$

$C = (P + o) \text{mod} 26$

$2 = (15 + o) \text{mod} 26$

$|o = |2-15| \text{mod} 26$

$o = 13$

So

$C = (P + 13) \text{mod} 26$

PLANET:

P

P is the 16th letter in the alphabet.

$C = (16 + 13) \text{mod} 26 = 3$

So P is coded C.

L

L is the 12th letter in the alphabet:

$C = (12 + 13) \text{mod} 26 = 25$

L is coded Y(25th letter in the alphabet)

A

A is the 1st letter in the alphabet

$C = (1 + 13) \text{mod} 26 = 14$

A is coded N

N

N is the 14th letter in the alphabet

$C = (14 + 13) \text{mod} 26 = 1$

N is coded A

E

E is the 5th letter in the alphabet

$C = (5 + 13) \text{mod} 26 = 18$

E is coded R

So the correct answer is:

1. CYNARG

Pls help due ASAP <br> Show workings

ElenaW [278]

Answer:

YW = 6

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 8^2 = 10^2

x^2 + 64 = 100

x^2 + 64 - 64 = 100 - 64

x^2 = 36

√x^2 = √36

x = 6
