X³ + 3x² = 25x + 75
x³ + 3x² - 25x - 75 = 0
x²(x + 3) - 25(x + 3) = 0
(x² - 25) * (x + 3) = 0
(x² - 25) = 0 (x + 3) = 0
x² = 25 x = -3
x = ±5
Hope this helps! :)
Since 3 < pi < 4,
<span>√9 < pi √16 </span>
<span>In fact, since pi^2 = 9.86, </span>
<span>√9 < pi < √10.
Which means the you</span><span> can find pi between square roots √9 and √10.</span>
Answer:
9
Step-by-step explanation:
three more than the sum of (3,3)
lets first do the sum of (3,3)
3 + 3 = 6
now it's asking<em> three more than the sum of (3,3)</em>
three more than means we need to add 3 to 6
6 + 3 = 9

6 cups of water : 4 cups of tomato sauce
1 cup: 4/6 tomato sauce
There are 2/3 cups of tomato sauce for every cup of water.
2n + 8 ≤ 25 |subtract 8 from both sides
2n ≤ 17 |divide both sides by 2
<u>n ≤ 8.5</u>
