Answer:
The answer to your question is the third choice
Step-by-step explanation:
To solve this problem, just multiply 6 by each of the numbers of the matrix and simplify.
6 | 4 -2 1 | = | (6 x 4) (6 x -2) (6 x 1) |
| 7 3 0| | (6 x 7) (6 x 3) (6 x 0) |
= | 24 -12 6 |
| 42 18 0 |
The first choice is wrong because only multiply by six the first row.
The second and fourth rows are incomplete.
The perimeter is 12 feet. This is because a square has equal sides. So if one side of the square garden is 3 feet then the other sides are 3 feet as well. To find the perimeter you add 3 + 3 + 3 + 3 (since there are four sides) and your answer is 12. Hope this helps!
<u>Answer:</u>
ΔLNM is proved as isosceles triangle. Below for explanation.
<u>Step-by-step explanation:</u>
We know that:
- AMBX = Square
- Squares have equal sides
Since AMBX is a square, AL must equal to BN because they are the extra lengths of the square. The lengths of the square are AM, MB, BX, XA.
- Side of square + Extra length = Side of triangle
This can tell us that the two sides of the triangle are equal. We also know that if 2 sides of a triangle are equal, it is classified as an isosceles triangle. Hence, ΔLNM is proved as an isosceles triangle.
Hoped this helped!
