The expression to simplify in this problem is
![7\sqrt[4]{80pq^2r^8}](https://tex.z-dn.net/?f=7%5Csqrt%5B4%5D%7B80pq%5E2r%5E8%7D)
Which can be rewritten as
Or also as
Now we can apply the following rule for the calculation of the power of a power:
So we get:
Which can therefore be rewritten as
And so, we get
which can be finally rewritten as
We can solve this by setting up 2 equations. We can use any letters like. For now, I'll use x and y.
So now we know that x - y = 0.7 and x + y = 1.
Now we can eliminate one of the letters by adding or subtracting one equation from the other. I am going to eliminate y by adding the two together (the y and the -y cancel).
This gives us 2x = 1.7, and so x = 1.7 ÷ 2 = 0.85
Finally, we can substitute x for 0.85 back into one of the original equations to figure out what y equals. I'm going to use x + y = 1.
So now we have 0.85 + y = 1, so y = 1 - 0.85 = 0.15
The numbers, therefore, are 0.85 and 0.15 (you can check by using the other equation).
Hope this helps!
Answer:
-68
Step-by-step explanation:
X/17=-4
X=-68
So the answer is -68
Answer:
25 sq. units
Step-by-step explanation:
Because it is a square, you only have to find one if its side lengths. Let's say you choose to find the distance between B and C. You'll be finding the length of a hypotenuse due to the fact that the two points are diagonal from each other. Use the x and y values to discover the lengths of the legs of the triangle. In this instance, they are 3 and 4. Using background knowledge of the properties of triangles, I know that the hypotenuse of a right triangle with legs of 3 and 4 must be 5. Therefore, the side length of this square is 5. To find the area of a square, simply multiply its side length by itself. 5 x 5 = 25!
