Answer:
-3
Step-by-step explanation:
Note that when you multiply two negative numbers, the answer will result as a positive number. Also note that when you multiply a negative number with a positive number, then your answer will result in a negative number.
(-1)(-1) = 1
(1)(-3) = -3
-3 is your answer.

Answer:
Both triangles have acute angles
Answer:
676π Sq. cm.
Step-by-step explanation:
The line GY is the radius of the circle with G as center and Y is a point on the circle.
Now, GY = 10 cm.
Again, the line XY is the radius of the circle with X as center and Y is a point on the circle.
Now, XY = 16 cm
The two circles touched at point Y,
Therefore, point Y will be on line GX.
Now, GX = GY + YX = 10 + 16 = 26 cm.
Therefore, Marco wants to create a new circle using GX as the radius, then the area of the new circle will be π (26)² Sq. cm. = 676π Sq. cm. (Answer)
Complement angles means that the sum of the two angles equal to 90°.
Thus,
x + 8x = 90
9x = 90
x = 10°
8x = 80°
The complement is 80°
Answer: (-1, -5)
Plug x into the equation:
y=I-1I-6
y=1-6
y=-5
Since this pair is the only one that is true, (-1, -5) is the answer.
