Answer:
The dimensions ⇒ 3 × 4
Step-by-step explanation:
* Any matrix has two dimensions
- Raw and column
- The dimensions very important in the operations on matrices
- We called the number of raw m and the number of column n
- We must write the number of raw before the number of column
- m × n is the dimensions of the matrix
* Example : If the dimension of a matrix is 2 × 3, that
means the matrix has 2 raw and 3 column
* Now lets look to our problem
∵ It has 3 raw and 4 column
∴ Its dimensions is 3 × 4
Answer:
B but am not sure tho it's probably A
It would be 11.25 inches because 1800 divided by 160 is 11.25
Answer:
(x - 3)² = 10
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
x² = 6x + 1
<u>Step 2: Rewrite</u>
- Subtract 6x on both sides: x² - 6x = 1
- Complete the Square: x² - 6x + 9 = 1 + 9
- Factor: (x - 3)² = 10
