Answer:

For step three she could multiply the two parenthesis against each other to get 3(x² - 10x + 25) - 2 + 4x

Step-by-step explanation:

step 1: 3(x - 5)² - 2 + 4x

step 2: 3(x - 5)(x - 5) - 2 + 4x

For step three she could multiply the two parenthesis against each other to get 3(x² - 10x + 25) - 2 + 4x

A square garden plot has an area of 24 ft2.
strojnjashka [21]
The area of a square is equal to the side squared.
s^2=A

We can plug in 24 for A and then take the square root of each side to find s.
s^2=24 \\ s=\sqrt{24}

We can simplify √24.
The prime factorization of 24 is 2×2×2×3.
Since we have 2×2 inside the radical we can simplify to have 2 outside the radical.
\sqrt{24}=\sqrt{4\times6}=\boxed{2\sqrt{6}\ ft}

We can then use a calculator to find an approximate decimal value for 2√6.
(You could technically calculate it by hand using the Babylonian method, I don't think you're expected to do that, though)
2\sqrt{6}\approx\boxed{4.9\ ft}

lesya692 [45]
The percentage would be 55.9% girls overall in the class because 19/34 as a percentage is 55.882352941177% but to round it would be 55.9%.

I hope this helped! Brainliest? :) -Raven❤️
