x = 9
x = 15
x = 4
x = 36 (assuming that says x = 12 * 3)
What you have too do is Times 40 by 25 for question 26
Answer:
m=21 and n=21
Step-by-step explanation:
In order to maximize the area of the rectangle, you want the two side lengths to be as equal to each other as possible.
In this case, we get that 2m+2n=84, so m+n=42. In our case, m and n can equal each other, so that gives us the maximum area of 441
Proof that this works:
If we had other dimensions, like m=20 and n=22, the area would be 440, slightly less than 442. If m=19 and n=23, the area becomes 437, which is even further off from 441.
Answer:
no
Step-by-step explanation:
because I know that and u donot
First you need to find a expression that gives you any number of sticks for a number(n) of houses. Start by looking at one house, then two and the third. You will see that the number of sticks is found by 4n + 1, and n is the number of houses.
So to find how many houses there will be if 61 sticks are used, you set 61 equal to the expression 4n + 1 and you should get n = 15
