The option (B) 2,-2 is correct because the number satisfy the provided expression.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a number bank shown in the picture.
The problem given:
7 - __ = 7 + __
A. 3,-4
Checking for the above option:
7 - 3 = 7 - 4
4 = 3 (false)
B. 2,-2
Checking for the above option:
7 - 2 = 7 - 2
5 = 5 (true)
O C. 1;-4
Checking for the above option:
7 - 1 = 7 - 4
6 = 3 (false)
D. 2; 3
Checking for the above option:
7 - 2 = 7 + 3
5 = 10 (false)
Thus, the option (B) 2,-2 is correct because the number satisfy the provided expression.

You set up the problem correctly, just keep going.
Expand out your expression:
2x(3x-9) + 4x(x+13)
= 6x^2 -18x + 4x^2 + 52x
= 10x^2 +34x
Remember that the above expression is the area, so it is equal to 24.
10x^2 + 34x = 24
10x^2 + 34x - 24 = 0 (divide by 2)
5x^2 + 17x - 12 = 0
Done.
Plot it to the nearest time so the answer is a
F : R -> R, f(x) = ( 2x - 3)( x - 3 ) => f(x) = 2x^2 - 9x + 9;
The axis of symmetry is x = - b / (2a) => x = 9 / 4.
Answer:
C. 5 × 3
Step-by-step explanation:
The order of a matrix is the number of rows and columns that a matrix has. Rows are listed first and columns are listed second. The matrix has 5 rows going across horizontally and 3 columns going down vertically.
So, the order of the matrix is 5 × 3.
Hope that helps.
