This answer is a lot easier to find if you write out the math. 5 to the second power (or 5X5) is 25 and 2 to the second power (or 2X2) is 4, so they add together for a sum of 29 (25+4=29). As for (5+2) to the second power, both five and two are taken to the second power, however when you distribute there are middle terms that result as well. A good way to approach it is to use the foil method, which stands for First, Outter, Inner, Last.
So (5+2) to the second power can also be written:
(5+2)(5+2)
First: 5X5 =25
Outter: 5X2 =10
Inner: 2X5 = 10
Last: 2X2 =4
And all of that adds up for a total of 49.

Because 5 +2 is 7 and seven to the second power is 49. On the other hand 5 squared is 25 and 2 to the second power is 4 when you ad them together you get 29 you are taking to completely different numbers to the power of two and that’s why they aren’t equal

PLEASE HELP!! WILL GIVE BRAINLIEST!!!
Murrr4er [49]

Answer:

option D

Step-by-step explanation:

Jerry solved this equation: 

3(x-\frac{1}{4})=\frac{13}{6}

In the first step , she multiplied 3 inside the parenthesis

1. 3x-\frac{3}{4}=\frac{13}{6}

In step 2, 3/4 is added on both sides

2. 3x-\frac{3}{4}+\frac{3}{4}=\frac{13}{6}+\frac{3}{4}

In step 3, we take LCD 12

3. 3x=\frac{26}{12}+\frac{9}{12}

In step 4, add the fractions

4. 3x=\frac{35}{12}

Here, 3 or 3/1 are same.

\frac{3}{1}x=\frac{35}{12}

In step 5, to remove 3/1 we multiply both sides by 1/3.

Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1

\frac{1}{3} \cdot \frac{3}{1}x=\frac{1}{3} \cdot \frac{35}{12}

x=\frac{35}{36}

In step 5, he should have multiplied both sides by 1/3
