Answer:
The correct answer is 450°, 810°, -270° and -630°.
Step-by-step explanation:
According to the given scenario, the calculation of the two positive angles and two negative angles i.e. coterminal is as follows:
The coterminal angles are the angles in which the difference could be 360 degrees or the multiples of 360 degrees
For 90 degrees, the two positive angles are
a. 90° + 360°
= 450°
450° + 360°
= 810°
b. The two negative angles are
= 90° - 360°
= -270°
-270° - 360°
= -630°
(2x-4)(x+5) expand with indicated multiplication
2x^2+10x-4x-20
2x^2+6x-20
500/20 = 25kcal per piece
8 * 25 = 200kcal.....yes, he is able to have 8 pieces
