I assume #3 is 19 because the slope of the line is still the same.
Hope this is right and it helps! I'm not very sure though.
There is an invisible +0 at the end. this means the y intercept is 0
The ninth term will be 71.
Answer:
x = 24
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
<em>a</em> = a leg
<em>b</em> = another leg
<em>c</em> = hypotenuse
Step 1: Plug in known variables
x² + 10² = 26²
Step 2: Evaluate
x² + 100 = 676
Step 3: Isolate <em>x </em>term
x² = 576
Step 4: Isolate <em>x</em>
√x² = √576
x = 24
