Answer:
-3x^2 +7x -4
-------------------------------
(x-3)(x-2)(x+3)
Step-by-step explanation:
2 3x
-------- - ----------
X^2-9 x^2 -5x+6
Factor
2 3x
-------- - ----------
(x-3)(x+3) (x-3)(x-2)
Get a common denominator
2 (x-2) 3x(x+3)
-------- - ----------
(x-3)(x+3)(x-2) (x-3)(x-2)(x+3)
2x-4 - (3x^2 -9x)
-------------------------------
(x-3)(x-2)(x+3)
Distribute
2x-4 - 3x^2 +9x
-------------------------------
(x-3)(x-2)(x+3)
Combine like terms
-3x^2 +7x -4
-------------------------------
(x-3)(x-2)(x+3)
Square have 4 equal sides length = a
A = 255
A = a^2
255 = a^2 |sqrt
15 = a
P = 4a
P = 4*15 = 60
D. 100% you’re just adding them both together
Answer:
- 2
Step-by-step explanation:
Step 1:
30 = - 5 ( 6n + 6 ) Equation
Step 2:
30 = - 30n - 30 Multiply
Step 3:
60 = - 30n Add 30 on both sides
Step 4:
n = 60 ÷ - 30 Divide
Answer:
n = - 2
