C is the hypotenuse, so the pythagorean theorem used would be: 15²=13²+6². 225=169+36, but 169+36 does not equal to 225, therefore the triangle is not a right triangle
The answer is <span>25; it represents the hourly wage for the worker
</span>
<span> y = 8x + 25
x is hours
y depends on x hours so y-intercept represent the hourly wage.
The y-intercept is y when x = 0:
y = 8x + 25
x = 0
____
y = 8 * 0 + 25
y = 0 + 25
y = 25</span>
8x9=72 ft squared
4x3=12 ft squared
72+12=84 ft squared
