Answer:
Step-by-step explanation:
i solve (a)
put x=2
3(2)³-4(2)²-5(2)+2=3(8)-16-10+2=24-26+2=0
so x=2 is one solution.
divide by 2 synthetically
2 |3 -4 -5 2
| 6 4 -2
|-------------------
3 2 -1 |0
3x²+2x-1=0
3x²+3x-x-1=0
3x(x+1)-1(x+1)=0
(x+1)(3x-1)=0
x=-1,1/3
so solutions are -1,1/3,2
Answer:
49.5 ounces the flower
3 pounds, 1.5 ounces
Step-by-step explanation:
Given that :
24 cupcakes 9 ounces of flower
Number of ounces of flower required for 132 cupcakes will be x
Using cross multiplication method :
24 cupcakes = 9 ounces
132 cupcakes = x ounces
Cross multiply :
24 * x = 132 * 9
24x = 1188
divide both sides by 24 to isolate x
x = 49.5
Hence, 49.5 ounces the flower is required for 132 cupcakes
To express in pounds :
1 pound = 16 ounces
49.5 ounces = 3 pounds 1.5 ounces
The answer is 10 radical 11
The answer would be T = -35
Answer:
C
Step-by-step explanation:
- 2 - 5 would represent a negative start, and further decreasing. So, a situation to describe this could be:
The temperature was -2°C and has <em>decreased</em><em> </em>by 5°C.
