When solving (-2)5(-2)-8, you would first, following PEMDAS ofcourse, multiply -2 and 5, getting -10. Then you would multiply -2 and -10, which would be positive 20. Lastly, you would subtract 8 from 20, which equals 12.
I cannot find an answer within the options you gave me, but I am 100% sure that (-2)5(-2)-8 equals 12.
Hope this helped in some way! Please mark brainliest! Thank you v much! :)

Answer:
90, 90, 90, 135, 135
Step-by-step explanation:
The sum of the measures of all angles is 540 deg.
The measures of the angles are: x - 45, x - 45, x, x, x - 45.
Add the expressions of the measures of the angles and set equal to the sum of the measures, 540 deg. Then solve for x. Then use the value of x to find each angle measure.
x + x + x - 45 + x - 45 + x - 45 = 540
5x - 135 = 540
5x = 675
x = 135
x - 45 = 135 - 45 = 90
Answer: 90, 90, 90, 135, 135
Answer:
4312
Step-by-step explanation:
7000-3096=3904
3904+408=4312
since BAD = 125
180-125 = 55 so ADC = 55
ADC = GHE so GHE = 55 degrees
