Answer:
<h2>w² - 2(w)(1) + 1² = w² - 2w + 1 = (w - 1)²</h2>
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
We have
w² - 2w = w² - 2(w)(1)
We must add 1²
w² - 2(w)(1) + 1² = (w - 1)²
C- $1.89
a & b aren't enough and d is too much
The associative property states : a + (b + c) = (a + b) + c....and this is what ur problem is.
L= length of one side of the square
Ok so we know the perimeter is 32 cm. Perimeter is the sum of all the sides of a shape. Now all four sides of a square are the same length. That means 4*L=32.
Now that we have the equation 4*L=32, we need to find a number that when multiplied by four, equals 32. Since 4*8=32, we know the answer must be 8cm.
