To get the product of a whole number itself, always multiply it twice to get the product. Example; 7 x 7 = 49.
Answer:
width = 5 ft
length = 9 ft
Step-by-step explanation:
Here, we want to get the length and width of the garden
length is 1 ft less than twice the width
if width = w
length = 2w-1
The product of the two is 45
so, we have it that;
w(2w-1) = 45
2w^2 - w = 45
2w^2 - w -45 = 0
2w^2 - 10w + 9w -45 = 0
2w(w-5) + 9(w-5) = 0
(2w + 9)(w-5) = 0
2w + 9 = 0
or w -5 = 0
w = 5 or-9/2
w cannot be negative, so we = 5
l = 2(5) -1 = 10 - 1 = 9 ft
Distributive property is when you are distributing the problem into a smaller problem. Associative property is when you have a problem with just addition or subtraction, and you can put the parenthesis anywhere and still get the same answer
For question (ii) I'm not sure if the answer is correct or not because I don't understand the question asked ...
I hope I can help ....
