Answer:

Option D is correct

Step-by-step explanation:

Using the given diagram, we want to know the equation that is true

Option A is wrong as both are on a straight line and in fact should add up to equal 180 and not be equal to each other

Option B is not correct as both are supplementary and does not equal each other

Option C is not correct, both are corresponding to each other and should not add up to 90

Option D is correct

Both angles are supplementary as they are exterior angles that add up to 180

The distances of a port from 20 differ- ent locations form an AP. If the farthest distance is 300 km, and the nearest distance i
Mkey [24]

Answer:

Required difference = 270/19 km

Step-by-step explanation:

If we consider the AP of distances to be

a, a + r, a + 2r, ..., a + 19r,

where a is the distance of the nearest location from the port and r is the difference between any two successive location.

Given that,

a + 19r = 300 .....(1)

a = 30 ..... (2)

Using (2), from (1), we get

30 + 19r = 300

or, 19r = 300 - 30

or, 19r = 270

or, r = 270/19

Therefore the distance between any two successive location is 270/19 km.

I will give BRAINLIEST for first correct answer!!! PLEASE answer as soon as you can :)
Digiron [165]

Answer:

(x+1)(x+2)

Step-by-step explanation:

x^2 + 3x + 2

find what multiples to 2 and adds to 3

Factors of 2 are 1 and 2, 2 + 1 = 3.

so the binomial would be (x+1)(x+2)

and then you would need to do FOIL to check

First: x * x = x^2

Outer: x * 2 = 2x

Inner: x * 1 = x

Last: 1 * 2 = 2

Then simplify: x^2 + 2x + x + 2

                          x^2 + 3x + 2
