Answer:
jesse's mistake is in Step 1
Step-by-step explanation:
She had to subtract 9 from 11, which would have got her 2, for the part after the equal sign. However, she put 3, and 11-9 is not 3, so she is wrong.

Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
Answer: 5
Step-by-step explanation:
Using the options use the Pythagorean theorem
5^ 2 + 12^2 = 25 + 144 = 169
Sqrt(169) = 13
8 + 5 = 13
answer: t = 5
Your answer is D. y = 36
We can find this by just rearranging the equation firstly:
2 + √4y - 3 = 11
√4y - 1 = 11
√4y = 12
Now we can simplify √4y, because 4 2², so you get 2√y :
2√y = 12
√y = 6
We can now square both sides to get the equation as "y ="
y = 36
