Answer:
21.5cm²
Step-by-step explanation:
First you find out the Area of the square itself which is 100cm² (squared). Then you Find the Area of the circle. The formula to find the area of a circle is π × Radius². So you find the diameter of the circle (which is 10) and divide that by 2 to find the radius. So the radius is 5 but then you need to square 5 which is 25. Then you multiply 25 with pi which is 78.5 so the area of the circle is 78.5cm². Now what you have to do is subtract the area of the square and the area of the circle to find the area of the shaded region. 100-78.5 is 21.5cm ² and that is the answer.
Answer: X= -9
Step-by-step explanation:
Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.
Then subtract or add the like terms
5x-3x and 20+3. It will be 2x+23=5
Then add -23 to both sides
It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x
2x/2=-18/2 then the final answer is x= -9. I hope it help
Answer:
x = 2/3
Step-by-step explanation:
Let's unpack the equation 
from our definition of 
:
(where 
)
Now that we've got things defined in terms of familiar operations, we can simplify and solve for x:
I would think it would be r
Answer:
Well, that is simple. You first must find the slope of the line from the 2 given points by using the slope formula. Which is y2-y1/x2-x1. So 2-4/-2-2 which equals -2/-4 which is 1/2. So the slope is 1/2. Now we can use the slope intercept form which is y=mx+b to find the slope equation. So we plug in one the points, say (2,4) and get y=1/2x+3. So now we plug in (6,y) Since we know x we can find y. y=1/2(6)+3 which gives us y=6. So y is 6.
