Answer:
8x^2+19x
Step-by-step explanation:
Simplify the expression by combining like terms. Terms which look a like and sound a like should be added together.
3x^2+7x+3+5x^2+12x
x^2 terms: 3x^2+5x^2=8x^2
x terms: 7x+12x=19x
constants: 3
Together is is 8x^2+19x+3.
The distance between B and B' will be the same as distance between A and A'.
= sqrt ( (5-1)^2 + ( 1 - -2)^2)
= sqrt (16 + 9)
= 5 units answer

Answer:
Step-by-step explanation:
Setting it up as a fraction will help us see the simplification process a bit easier.
a/a = 1, so they cancel each other out, leaving us with simply
Length of AC is 5 I hope this helps I can’t think right right now so bare with me
