Answer:
<h2><u>[D] 13.9</u></h2>
Explanation:
- <em>Pythagorean theorem: a² + b² = c²</em>
- <em>Solve for hypotenuse (side x) using: c = √a² + b²</em>
12.8² + 5.3² = 191.93
√191.93
= 13.8538803229
<em>Round the answer</em>
13.9
-5/-7 = 5/7 = 0.71428577142857... The decimal form of the fraction never ends, so 5/7 is not a rational number
Two point three mequals zero point fourty six
The integer is positive 4.
B/c-
4 • 4 = 16
In standard form it would be x + 2y = 8.
x + 2y = 8
2y = -x + 8
y = -1/2x +4
