We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:


This is, indeed correct, thus, this
<em>is </em><em>
a right triangle.</em>
We can divide each digit by 7. So 56/7=8 and 21/7=3
so.... 8:3
The correct answer is
<span>D. The number of degrees in its supplement
The size of the sides and the rotation is irrelevant and would still keep the angle having the same size. The number of degrees in the supplement decides how big an angle is because the larger the supplementary angle the smaller the angle we're observing will be, and vice versa.</span>
F(x) = 3x + 9
g(x) = 5x²
(f + g)(x) = (3x + 9) + 5x²
(f + g)(x) = 3x + 9 + 5x²
(f + g)(x) = 5x² + 3x + 9
Answer:
100
Step-by-step explanation:
Put the values where the corresponding variables are, then do the arithmetic.
(-4 -2)^2 +(3 -(-5))^2
= (-6)^2 +(8)^2
= 36 +64 = 100
