Answer:
2.89
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.
First, subtract 12 from both sides:
25 = 4.5z + 12
25 (-12) = 4.5z + 12 (-12)
25 - 12 = 4.5z
13 = 4.5z
Isolate the variable, z. Divide 4.5 from both sides:
(13)/4.5 = (4.5z)/4.5
z = 13/4.5
z = ~2.89 (rounded).
2.89 is your answer.

Length of rectangle: 4x+3
Perimeter of rectangle: 12x+10
Solving:
4x+3 + 4x+3= 8x+6
Now we have 8x+6 but, we still need our width.
12x+10 - 8x+6 = 4x+4
So now, since we only have 4x+4 left for our width, we are going to divide that by 2 because in a rectangle, there are 2 lengths and 2 widths.
So in conclusion, the width of the rectangle is 2x+2
Glad I could help!
And also, can you please mark my answer as the brainliest answer?

Answer:
O B. 17 units
Step-by-step explanation:
The chord is AC and the radius of the circle is perpendicular to the chord at B. AB = 8.5 units. According to the perpendicular bisector theorem, if the radius of a circle is perpendicular to a chord then the radius bisects the chord. This means that chord AC is bisected by the radius of the circle at point B. The length of the circle is calculated using:

The length of the chord is 17 units.
