Answer:2739
Step-by-step explanation:
x³ + 2x² - 9x - 18 = 0
x²(x+2) - 9(x+2) = 0
(x + 2)(x² - 9) = 0
(x + 2)(x - 3)(x + 3) = 0
the answer is d.
Answer:
14.5
Step-by-step explanation:
10 + (2 x 3)2 ÷ 4 × (3 x 1/2)
10 + (6)2 / 4 * (1.5)
10 + 12 / 4 * 1.5
10 + 3 * 1.5
10 + 4.5
14.5
frac(4)(5) so I'll just assume it's 4/5 cup of rice per serving if you didn't make any misspells.
To calculate the amount of servings you can make for 5 cups of rice, you take the amount you have and divided by the amount of cups needed per serving
-> 5 : 4/5 = 6.25
Because it says "full servings", we round it down to 6. Therefore, with 5 cups of rice, you can make 6 full servings of bibimbap.
Answer:
63
Step-by-step explanation:
If x units, then 2x tens
Number is: 2x(10)+x = 21x
Reversing digits:
2x units and x tens,
Number is: x(10)+2x = 12x
21x - 12x = 27
9x = 27
x = 27/9 = 3
Original number: 21x = 21(3) = 63
