Answer:

124

Step-by-step explanation:

(ab)^2 + (b^3 - a^2)

Let a = -2  and b = 4

(-2 *4)^2 + (4^3 - (-2)^2)

Parentheses first

(-8)^2 + (4^3 - (-2)^2)

Then the exponents in the parentheses

(-8)^2 + (64 - 4)

Subtract in the parentheses

(-8)^2 + (60)

Exponents

64 + 60

number of seating arrangement for martians is 4!

number of seating arrangement for plutonians is 3!

number of seating arrangement for jupiterians is 5!

total number of seating arrangement is 12!

so, we get

possible seating arrangements are

=\frac{12!}{4!3!5!}

Answer:

B) AB is parallel to CD, but AD is not parallel to BC.

Step-by-step explanation:

The options are:

A) AD is parallel to BC, but AB is not parallel to CD.

B) AB is parallel to CD, but AD is not parallel to BC.

C) AB is parallel to CD, and AD is parallel to BC.

D) AD is not parallel to BC, and AB is not parallel to CD.

AB and CD have the same slope, so they are parallel.

BC and AD have different slopes, so they are not parallel.

Therefore, the answer is B.

if PQ || RS and the slope of PQ= x-1/4 and the slope of RS is 3/8 then find the value of x justify algebraically and numerically
Artemon [7]

The value of x is 5/8.

<u>Step-by-step explanation</u>:

Given,

  • The lines PQ and RS are parallel to each other.
  • slope of PQ= x-1/4
  • slope of RS = 3/8

The slopes of parallel lines are equal.

slope of PQ = slope of RS

⇒ x-1/4 = 3/8

⇒ (4x-1)/4 = 3/8

⇒ 8(4x-1) = 4(3)

⇒ 32x-8 = 12

⇒ 32x = 20

x = 20/32

x = 5/8
