Answer:So what is the question?
Step-by-step explanation:
Answer: Choice A, x=-4
Step-by-step explanation:
1. 9x−(3x+9)=2x−25
2. 9x-3x-9=2x-25
3. 6x-9=2x-25
4. 6x-9=2x-25
-2x -2x
5. 4x-9=-25
+9 +9
6. 4x=-16 (divide both sides by 4)
7. x=-4

Answer:
See explanation, and comment for more details!
Step-by-step explanation:
10. The perimeter of any shape is the sum of the length of the sides, which means that the perimeter of this triangle is x+y+z.
11. Since this is a right triangle, the two legs form the height and base. The area of this triangle is therefore x*y/2.
12.
a. x=3, y=4, z=5
b. ![x=\sqrt{2}, y=\sqrt{2}, z=2](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B2%7D%2C%20y%3D%5Csqrt%7B2%7D%2C%20z%3D2)
c.![x= \sqrt{3}, y=2, z=\sqrt{7}](https://tex.z-dn.net/?f=x%3D%20%5Csqrt%7B3%7D%2C%20y%3D2%2C%20z%3D%5Csqrt%7B7%7D)
Hope this helps!
Answer:
x = plus or minus √7
Step-by-step explanation:
Solve the equation 7x^2=49, starting out by dividing both sides by 7. This results in x^2 = 7.
We need to solve for (isolate) x. To do this, take the square root of both sides:
x = plus or minus √7
