Answer:
Hence the expression
Step-by-step explanation:
Explanation
- The given expression is (a + b)(2a+3 b).
- We have to multiply the given expression.
- Multiply the (a + b) by 3b, multiply the (a + b) by 2a then add like terms.

To solve this problem you must apply the proccedure shown below:
1. You must apply the Law of Cosines, as you can see in the figure attached. Then:
- The first ship travels at in for two hours. Therefore, the side is:
- The second ship travels at for . Therefore, the side is:
- Now, you can calculate :
The answer is:
Answer:
After the reflection over the line y = -x, the image of the point is: (-3,-2)
Step-by-step explanation:
When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.
Let (x,y) be a point on the plane
and
y = -x be a line on the plane
When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated
So (x,y) will become (-y,-x)
Given point is:
(2,3)
After the reflection over the line y = -x, the image of the point is: (-3,-2)
