The answer is b because it’s b
Answer:
8 positive integers.
Step-by-step explanation:
One value of n would be 15 because 225 = 15^2.
Other values are 225 * n where 15n <= 1000 and n is a perfect square.
So n = 4 gives us 225* 4 = 900 which is a perfect square and 15*4 = 60.
n = 9 gives us 225 * 9 which is a perfect square and 15*9 = 135.
n = 16 gives us 225*16 and 15*16 = 240 , so OK.
n = 25 gives a perfect square and and 15*25 = 375 - so OK.
n = 36 gives a perfect square and 15*36 = 540 - so OK.
n = 49 gives a perfect square and 15*49 = 735 - so OK.
n = 64 gives a perfect square and 15*64 = 960 - so ok.
n = 81 gives a perfect square and 15 * 81 = 1215 so NOT ok.

Answer:

Step-by-step explanation:
Given: tape diagram
To find: an equation to represent the image
Solution:
In the image, the area of the tape diagram indicating 1.75 is equal to the sum of areas of all the five parts in the diagram such that each part indicates n.
So, according to the given information, the equation is
.
Here, we have assumed that 1.75 represents an area of the first rectangle, and n represents the area of each of the small rectangle.
