Answer:
x=4
Step-by-step explanation:
The first thing you need to do is combine like terms which would give you
3x-4=8 then you would add four to both sides giving you 3x=12 finally you would divide both sides by 3 giving you x=4.
Answer:
triangle SAT is congruent to triangle SAO, because of SAS congruence criterion
given angle AST = angle ASO
ST = SO
SA = SA (common side)
therefore using the two sides and the angle included, triangle SAT congruent to triangle SAO.
$42 what you do is take $1400 times .03 which equals 3 percent and you get 42.

Answer:
-6 = x
Step-by-step explanation:
3 sqrt (5x-4) = 3 sqrt (7x+8)
Divide each side by 3
3/3 sqrt (5x-4) = 3/3 sqrt (7x+8)
sqrt (5x-4) = sqrt (7x+8)
Square each side
(sqrt (5x-4))^2 = ( sqrt (7x+8) )^2
5x-4 = 7x+8
Subtract 5x from each side
5x-5x-4 = 7x-5x+8
-4 = 2x+8
Subtract 8 from each side
-4-8 = 2x+8-8
-12 = 2x
Divide by 2
-12/2 = 2x/2
-6 = x
