Answer:
<h2>
Marianna is incorrect because x2</h2><h2>
2x13 can be factored into two binomials</h2>
Step-by-step explanation:
ax^2+bx+c = 0
x=−1+√14 or x=−1−√14
discriminant=56
completing square x=−1+√14 or x=−1−√14
Now, we can solve each term for
x=-2 she is incorrect
x(x+2)=0
Now, we can solve each term for
0:
x=0
- no other work needed,
and
x+2=0
x+2-2=0-2
x+0=-2
<u>x=-2</u>

Answer:B
Step-by-step explanation:
All you have to do is multiply
If you would like to solve the equation 13 - 3 / 2 * x = 34, you can do this using the following steps:
13 - 3 / 2 * x = 34
13 - 34 = 3 / 2 * x
- 21 = 3 / 2 * x /* 2/3
x = - 21 * 2 / 3
x = - 14
The correct result would be - 14.
Answer:
It will take 5 stages to reach the surface.
Step-by-step explanation:
-225/50=4.5 or what times 4.5 equals -225
Then the problem says to round up so 4.5 becomes 5.
Answer: 1/4 full.
Step-by-step explanation:
The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.
There is currently 3/4 of the tank remaining.
To find 2/3 of 3/4, you can multiply the fractions together.
Do this by multiplying both numerators and both denominators:

Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).
3/4 - 2/4 = 1/4
There will be 1/4 of the tank left.
