the answer is: < 1.8 repeating is greater that the square root of 2
The fourth step is incorrect.
<h2>Polynomial</h2>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Given
x² + 4x -12 is a polynomial.
<h3>How to factorize the polynomial?</h3>
x² + 4x - 12
Step 1. x² + 6x - 2x -12
Step 2. (x² + 6x) - (2x + 12)
Step 3. x(x + 6) - 2 (x + 6)
Step 4. (x + 6)(x - 2)
Thus, in fourth step in place of (x + 2), (x - 2) is to be put.
Thus, The fourth step is incorrect.

Given:
Seven equal-sized square photos arranged in a row to form a rectangle.
Total area of the collage is 567 square inches.
To find:
The length of the collage.
Solution:
Let the side of each square be x inches.
Seven equal-sized square photos arranged in a row to form a rectangle.
So, length of rectangle is 7x and width is x.
Area of rectangle is





Taking square root on both sides, we get


Side cannot be negative. So, x=9 inches.
Now,
Width = 9 inches
Length = 7(9) = 63 inches
Therefore, the length of the rectangle is 63 inches.
If in one hour Belinda can go 10 miles that means in 30 minutes she can go 5 miles. 60/2=30 10/2=5
If she can go 5 miles is 30 minutes than by doing some simple math she must be able to go 2.5 miles in 15 mins. 30/2=15 5/2=2.5
Meaning that when you add 30+15 you get 45 and when you add the distance she can go in each amount of given time 5+2.5 you get 7.5
- So the trail has to be 7.5 miles long
