Answer:
3
Step-by-step explanation:
Solve for x:
-6 + x = -3
Add 6 to both sides of the equal sign so -6 cancels out on the left side
+6 - 6 + x = -3 + 6
x = - 3 + 6
x = 3
I hope this helps! Good luck with your schoolwork :)
Answer:153.9 cm
Step-by-step explanation:
The area of a circle is found by pi × radius squared and pi is aprox 3.14 so 3.15×7² = 153.86 then round off to the nearest tenth you get 153.9
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.

Step-by-step explanation:
Answer:
164 sq. meters
Step-by-step explanation:
So to make it easier, you can break the shape up in a smaller shape. So now it'll look like 2 big rectangles on each side with a small rectangle in the middle. Now you can find the area.
For the big rectangle on the left:
5 × 15 = 75
For the big rectangle on the right:
5 × 15 = 75
For the small rectangle in the middle:
It doesn't say what the length is but if you subtract 8 from 15, that's what the length will be.
15 - 8 = 7
L = 7
7 × 2 = 14
Now add all the areas up.
75 + 75 + 14 = 164
