Answer:
5/2
Step-by-step explanation:
Answer: x(0.55)
Step-by-step explanation:
Because 45% of the price is being taking, off we are still paying for 55% of the market price, because 100%-45%=55%.
55/100=0.55
So the sale price is x(0.55)
Y = 2x² + 30x + 200
y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)

X=12.9 rounded
Explanation: 30/7=x/3
90=7x
90/7=12.85...
X=12.9 when rounded to nearest tenth
