Answer:

Step-by-step explanation:

Count pairs (a, b) whose sum of squares is N (a^2 + b^2 = N)

Given a number N, the task is to count all ‘a’ and ‘b’ that satisfy the condition a^2 + b^2 = N.

Note:- (a, b) and (b, a) are to be considered as two different pairs and (a, a) is also valid and to be considered only one time.

Examples:

Input: N = 10

Output: 2

1^2 + 3^2 = 9

3^2 + 1^2 = 9

Input: N = 8

Output: 1

2^2 + 2^2 = 8

Find the area of the triangle given below.
Nimfa-mama [501]

<u>Given:</u>

A triangle with a base length of 22 ft and a height of 20 ft.

<u>To find:</u>

The area of the given triangle.

<u>Solution:</u>

The area of a triangle is obtained by multiplying \frac{1}{2} with its base length and its height.

The area of a triangle = \frac{1}{2} (b)(h).

The height is the distance from the base to the highest point on the triangle and the length of the base is the base length.

The given triangle has a base length of 22 ft and a height of 20 ft.

The area of the triangle = \frac{1}{2} (b)(h) = \frac{1}{2} (22)(20).

\frac{1}{2} (22)(20) = \frac{1}{2} (440) = 220 ft².

The given triangle has an area of 220 ft².

Simplify the expression by combining like terms.
Tju [1.3M]

Answer:

8x + 13

Step-by-step explanation:

"Like terms" means the same kind of algebraic expression...the 6x and the 2x are "like terms" because they both have an x in them. The 9 and the 4 are both constants, which means they are plain numbers. So 6x and 2x is 8x .

9+4 is 13 just like elementary school.

So all together,

6x + 9 + 2x + 4

6x + 2x + 9 + 4

8x + 13

We can rearrange the terms because the problem has all addition in between the terms.
