A group of cubes are arranged in a pattern with the same number of cubes in each row and column. There are 225 cubes in the shape. How many cubes are in one row?
A)
15
B)
25
0
56
D)
75

Given:

Total number of cubes = 225

Cubes are arranged in a pattern with the same number of cubes in each row and column.

To find:

The number of cubes in a row.

Solution:

Let the number of cubes in a row be x.

Since, cubes are arranged in a pattern with the same number of cubes in each row and column, therefore number of cubes in rows and columns are equal.

Total number of cubes = 225

Taking square root on both sides.

So, the number of cubes in a row is 15.

Therefore, the correct option is A.

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

i think the answer is b.

step-by-step explanation:

not 100% sure though.
