Answer:
-7.14
Step-by-step explanation:
Evaluate
−4.2(−2.8 + 4.5)
Open parenthesis
(-4.2 * -2.8) + (-4.2 * 4.5)
= (11.76) + (- 18.9)
= 11.76 - 18.9
= -7.14
NOTE:
Negative (-) × negative (-) = positive (+)
Positive (+) × positive (+) = positive (+)
Negative (-) × positive (+) = negative (-)
Positive (+) × negative (-) = negative (-)
(5/6) x = -1/6 (multiply times 6/5)
x = -1/5
The angle of 25° is the complement of the angle of 65° and the angle of 65° is the complement of the angle of 25°.
The shortest distance between 2 concentric circles is the difference of their radii. Thus the answer is 8-2=6
