-7 is the not the solution.
If you plug in -7 into the equation, you get -11, which doesn't equal 17.
<span>8 (1/4x+ 3/4) - 3 = 17
</span>
8 (1/4(-7)+ 3/4) - 3 = 17
8 (-7/4 + 3/4) - 3 = 17
8 (-4/4) - 3 = 17
8 (-1) - 3 = 17
-8 - 3 = 17
-11
17

Answer:
X=121
Step-by-step explanation:
Reorder √x + 20 so highest orders Term are first
20+√x=9
We need to group all the variables term on one side and constant term at the other side. Therefore move the term 20 to the other side of equation 20+√x=9
√x=9-20
√x=-11
Eliminate the root
X=121
A circumscribed angle is that which is formed by the intersection of the two tangent lines in a circle. With this, we can conclude that segments AC and AB are tangent to circle O. The tangent lines forms a right angle with the radius of the circle drawn from the center of the circle to the tangent point.
By the explanation above, we can say that angles C and B are equal to 90° and that triangle ACO and triangle ABO are congruent. Which means that segment AC is equal to segment AB. Thus, the length of AB is also 4.
<em>Answer: 4 units</em>
