If x² = 196, then we must do the inverse (square root) to find x. However, the square root of any positive number will always be ± (plus or minus).
That means you have to do:
√196 = x
x = <span>±14.
We can check this by doing:
14 </span>× 14 = 196
-14 × -14 = 196
Therefore the answer is B) -14, 14.
Complementary angles are two angles that total 90°, so yes, you are correct.
ANSWER: The answer is (B) the sum of the measures of the two angles is 90°.
Hope this helps! :)
B = 16
x^2 + 16x + 64 can be factored down to (x + 8)^2.
Volume= lxwxh
v= 6cm x 6cm x 6cm (all are 6 because it is a cube, so all sides are equal)
v= 216 cm³
