1. I think the distance is 5 miles because the y-axis points for both coordinates are the same, and the difference between the x-axis points is 5; 9-4=5

2.
a. (3, 1) and (3, 5) because if you remove the -, it will be (3, 1) and (3, 5).
b. (-2, -6) , (-2, -10) , (2, 6) , and (2, 10).

b. All you have to do is get 2 points that are negative, and for the other 2 coordinates, remove the negative sign.

Hope this helped☺☺

Answer:

henc X = 30°

Step-by-step explanation:

here is the proof

when X=30° then

sin2x = sin2×30

=sin 60°

= √3/2

or else,

putting value of X = 30° then

sin2x= 2sinxcosx

= 2×sin30°×cos30°

=2×1/2×√3/2

= 2√3/4

= √3/2

hence proved sin2x= √3/2.

Ab+bc=<br> this is adding of like terms
stellarik [79]

Answer:

(a+c)b OR it's already on simplified form

Step-by-step explanation:

depending upon what your instructor wants, they may want you to say it's already simplified (which happens sometimes).

HOWEVER, if you know how to factorize (which is essentially un-distributing), you could factor out the b which is common in both.

ab + bc \\  = b( \frac{ab}{b}  +  \frac{bc}{b} ) \\  = b(a + c)
