The answer is
f(x) = 9x3 + 18 x2 - 135x can be written as f(x) = x( 9x2+ 18 x - 135)
the first zero must be = 0
let's find the another zeros by solving 9x2+ 18 x - 135=0
f(-5)=135-135=0, so the answer is
<span>
0, -5, and 3
because </span><span>f(x) = 9x3 + 18 x2 - 135x =x (x+5)(x-3)</span>
Step-by-step explanation:
125cm = 1.25m.
2m : 1.25m = 8:5
Answer:
d ≤ -0.5
Step-by-step explanation:
Multiply each term by -1
Answer:
$29.78
Step-by-step explanation:
1. make the % into a decimal
9.25% = 0.0925
2. multiply amount by the decimal to get the tax amount
$27.26 × 0.095 = $2.52
3. take the original amount and add the tax to get your final total
$26.27 + $2.52 = $29.78
X= 13.5
Every triangle equals 180 degrees. 23+23= 46. 46 - 1= 45. Then you solve the equation 10x+45=180 which would equal, 13.5.
