Answer:
2
Step-by-step explanation:
(8-x)(8+x)
8×8=64
-x·+x=-x^2
64-x^2
Answer:
Area = 7 square units
Perimeter = 14 units
Step-by-step explanation:
The shape is made up of 7 identical squares and, we are told the side length of each square is 1 unit.
==>Find area of the shape by calculating the area of 1 square, then multiply by the number of square used in the construction.
Thus, area of 1 square = s² = 1² = 1 square units.
Area of shape = 7 × 1 square units = 7 square units
==>Find the Perimeter of the shape by adding all the lengths of the boundary formed by the square to make up the shape.
(Check attachment to understand how we got the measurement of the boundary)
<em>The perimeter = 1 + 1 + 1 + ½ + ½ + 1 + 1 + 1½ + ½ + 1 + 1 + 4 = 14 units</em>

Answer:
9/8, 18/16, 27/24, 36/32, 45/40, 54/48, 63/56, 72/64, 81/72, 90/80, and so on ...
Explanation:
Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 18/16 is equal to 9/8 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/8) by the same integer number, ie, multiply by 2, 3, 4, 5, 6 ...
18/16 is equivalent to 9/8 once 9 x 2 = 18 and 8 x 2 = 16
27/24 is equivalent to 9/8 once 9 x 3 = 27 and 8 x 3 = 24
36/32 is equivalent to 9/8 once 9 x 4 = 36 and 8 x 4 = 32
