Answer:
The answer to your question is:
Step-by-step explanation:
12.-
x² - 6x = 5
x² - 6x + (3)² = 5 + (3)²
x² - 6x + 9 = 5 + 9
(x - 3)² = 14
13.- x² - 6x = 12
x² - 6x + (3)² = 12 + (3)²
x² - 6x + 9 = 12 + 9
(x - 3)² = 21
x - 3 = ±√21
x1 = √21 + 3 x2 = -√21 + 3
x1 = 7.58 x2 = -1.58
14.- 2x² - 24x = - 20 Divide by 2
x² - 12 x = -10
x² - 12x + (6)² = - 10 + (6)²
x² - 12x + 36 = - 10 + 36
( x - 6) ² = 26
x - 6 = ±√26
x1 = √26 + 6 x2 = -√26 + 6
x1 = 11.1 x2 = 0.9
Answer:
Step-by-step explanation:You can first divide 15 by 5, which equals 3.Then multiply that by 10.8.which gives 32.4. Then divide by 5 which would give you 2.16. Hopefully it helps?!
Also if it is right,Please make me brainliest!!!!!!!!!!!!!!!!!!!
Answer: the slope intercept form of 2x+y=6 is y=-2+6
Step-by-step explanation:
2x+y=6 (subtract 2x from both sides)
-2x -2x (the -2x and the 2x cancel leaving...)
<u><em>y=-2x+6</em></u> →( y equals negative two x plus six)
Answer:
I'm not sure if you're looking for an approximation or the exact amount, so I'll give you both. The drama club would need exactly 9.375 lbs of chocolate for the 75 orders, or 6.375 more lbs. If we round that up to the nearest pound, the club would need 10 lbs of chocolate to cover the 75 orders, with some left over. So, they would need 7 lbs more.
The third side is 9 cm long
Let represent one of the equal sides. Then the` other side will be .
Adding all the length of the sides should give 23. Thus,
This implies that,
We group like terms and simplify to obtain.
Divide through by 4 to get
Hence the length of the other side is
