Answer:
191=266+109x
Step-by-step explanation:
It says 191 is the same as 266 added to the product of 109 and _____. i am guessing you meant to say a variable.
The answer is -16 I believe (;
You don't say whether this is a right triangle or not.
Assuming it is a right triangle, then we use the Pythagorean Theorem to determine the length of the hypotenuse:
(hypo) = (length of third side) = √(12^2 + 4^2) = √(144+16) = √160 = 4√10.
This is approx. 12.65 inches. Since this does not match any of the possible answer choices, we'll have to take a different approach to answering this question.
Given that 2 sides of the given triangle are 12 and 4 inches, respectively, we see that the 3rd side has to be longer than 8 inches; otherwise we'd have three line segments on the same line, not forming a triangle.
By this reasoning, 9 inches is the only possible answer that could be correct. With sides 12, 9 and 4 inches, the triangle would be obtuse and appear quite flat, but not be part of a straight line as with a third side of 8.

Answer:
c= 25, solutions: x = 3, x= -13
Step-by-step explanation:
(10/2) ^2 = 25
(x+5)^2 = 64
