The right simplified expression is j - 10
Simplified expression is the simplest form of the equation. We need to group the variable before simplifying equations that have different variables, for example :
a + b + a + c + b
it can be simplified as
a + a + b + b + c = 2a + 2b + c
From the question above, we know that :
( j-8)-2
First, group the same variables
j - 8 - 2
= j + (-8 -2)
= j - 10
Hence, the right simplified form is j - 10 .

Answer:
-8
Step-by-step explanation:
-3x + 7x - 8 = 34 + 9x - 2
-3x + 7x - 9x = 34 - 2 + 8
-5x = 40|: (-5)
x = -8
Step-by-step explanation:
Okay! Since these are similar figures we need to find the scale factor in order to answer this question.
We have a triangle with sides 7, 4, and 9. The longest side is 9. This corresponds with the longest side on the similar triangle, which is 36. So to find the scale factor we divide 36 by 9. The scale factor is 4.
Now to find the shortest side of the bigger triangle, we have to find the length of the shortest side on the smaller one which is 4. Since our scale factor is 4, we multiply 4 by 4 to get 16.
The length of the shortest side of the similar triangle is 16
Answer:
D
Step-by-step explanation:
sin A = opp. /hyp. = CB/AB = 12/ 15 so CB =12 and AB=15
apply Pythagorean Th. for triangle ABC to find AC
AC²= AB²-CB² = 15²-12² = 81; AC = √81=9
tan A = opp./adj. = CB /AC = 12/ 9 = 4/3
