The length of AB is 25 units
<h3>How to determine the length AB?</h3>
The given parameters are
AC = 15 cm
BC = 20 cm
The triangle is right -angled at C.
So, we have:
AB^2 = AC^2 + BC^2
This gives
AB^2 = 15^2 + 20^2
Evaluate
AB^2 = 625
Take the square roots
AB = 25
Hence, the length of AB is 25 units

I dont know if I'm right or not but I believe the answer is b, because you cant solve for x with only these numbers.
Answer:
x = -8
Step-by-step explanation:
-6 - 4x = 26
- 4x = 32 add 6 to both sides
x = -8 divide both sides by -4 to isolate the variable
The easiest way to do this is by graphing the equation. I'll do it:
We see that the y intercept is 11.
Formula for slope-intercept: y = mx + b
mx = slope
b = y-intercept
Now we have y = mx + 11. What's mx? We can find that out from the graph.
Let's find two points: (0,11) (4,3)
Using <span> (y2 - y1)/x2 - x1): We see that the slope is -2.
Now we finish the slope-intercept form and plug it all in:
y = -2x + 11

Answer: 7pi
Step-by-step explanation: If it completes the circumference distance (14pi) of the circle in 20 seconds, in 10 seconds it will complete half of that. or 7pi. Hope this helped!
