So you need to turn 5x^2 -3x -9 into 2x - 3.
Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).
Then -3x needs to become 2x by adding 5x (+5x).
Finally -9 needs to become -3 by adding 6 (+6).
Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6
Answer:
The answer is 3.
Step-by-step explanation:
1. You need to substitute the values into the equation
2. You would then have 1/2(4-3(-2))-2
3. Now you have to multiply 3×-2 and you will now have 1/2(4+6)-2
4. Then you have to add what's in the parenthesis and you will have 1/2(10)-2
5. Now multiply 1/2(10) and uou will have 5-2
6. Now subtract 5-2 and that will = 3
(There is also a picture of how I worked it out)
The whale is 24.54 feet away from the shoreline.
Step-by-step explanation:
Step 1:
The man is 200 feet from the ground and the angle at which he sees the whale is 7°.
So a right-angled triangle can be formed using these measurements. The angle of the triangle is 7° while the opposite side of the triangle measures x feet while the adjacent side of the triangle measures 200 feet.
We need to find the opposites side's length of the triangle.
Step 2:
Since we have the length of the adjacent side and need to calculate the length of the opposite side we use the tan of the given angle.
The opposite side of the triangle = x feet.
So the whale is 24.54 feet away from the shoreline.
Answer:
A hexagon has six angles. A full circle is 360°; since there are 6 angles in the hexagon, it will rotate onto itself every 360/6 = 60°. This means that the hexagon will rotate onto itself at angles that are multiples of 60°; this means that 120° and 180° will also do this.

4 up and 6 right
