The correct answer is A. 7


Explain

11+17= 2 (21-x)

28= 2 (21-x)

Divide by 2

21-x = 28/2

21- x= 14

21-x = 14
Add x-14

X= 21-14

X= 7

Hope this help you :D

Use complete sentences to explain how you could use a number line to explain why 2 < 3 < 5. Please. :D
Svetach [21]
Two is less than three which is also less than 5.


When put into a number line from 0 to 10, it shows that 2 is closest to 0 while 5 is closest to 10 and three, will be in between 2 and 5. This shows that as you go from 2 to 3, the number increased and, it continues to increase when you go from 3 to 5. This shows that 2 is less than 3 and 3 is less than 5.

Answer:

48x + 216 square inches.

Step-by-step explanation:

Area is length X width.

Area is (4x + 18)(12).

in 4x + 18, 18 comes from adding the three 6 in.

We have no values for "x", so expand the equation and simplify.

(4x + 18)(12)

= 48x + 216

I can't figure this one out....Find ALL polar coordinates of point P = (6, 31°). The explanations I've found thus far don't seem
arsen [322]

Check the picture below.

so, as I see it, we can simply move from the point P, 360° counter-clockwise, the green one, and we'll be landing on a positive angle on the 1st Quadrant, the angle of 360° + 30° = 390°.

we can also move 360° clockwise, the red one, from P, so we'll be landing at -360° + 30 = -330°, also on the 1st Quadrant, but a negative counterpart.

now, if we move by jumps of 360° on either direction, we'll be landing coterminal with P all the time, so if we use simply multiply 360° by "n", some integer, then that angle added or subtracted from 30°, will be coterminal with P.

( 6 ,  30°±360n°)   where n ∈ ℤ.
