Answer:
Yes
Step-by-step explanation:
There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.
Answer:
Perimeter ratio = 2:1
Area ratio = 4:1
Step-by-step explanation:
<u>Perimeter</u>
Perimeter of the smaller photo =
inches
Perimeter of larger photo =
inches
Ratio:
Perimeter of larger photo : perimeter of smaller photo =
<u>Area</u>
Area of smaller photo =
inches²
Area of larger photo =
inches ²
Ratio
Area of larger photo : area of smaller photo =
∴The ratio of the perimeters = 2:1, and the ratio of the areas = 4:1
