Hey, here are all the problems. Im not sure how to do this and my teacher isnt giving me much time. Help would be apricated (9x + 5) - (-8x - 11)
(-5x - 7) + (-2x + 6)
(-x - 9) - (5x + 4)
(3x - 4) - (x - 7)
(7x + 4) - (5x + 5)
(2x - 3) + (7x + 11)
(-4x - 5) + 2(3x - 4)
2(6x - 7) - (2x + 3)
(5x + 4) - (5x + 12)

Answer : (9x + 5) - (-8x - 11) is 17x + 16

explanation: 1st, distribute 2nd, eliminate redundant parentheses 3rd, add the numbers 4th, combine like terms.

(-5x - 7) + (-2x + 6) is -7x - 1

explanation : just do the same as every other one

(-x - 9) - (5x +4) is -6x - 13

explanation : 1st, distribute 2nd, eliminate redundant parentheses 3rd, subtract the numbers 4th, combine like terms.

(3x - 4) - (x -7) is 2x + 3

explanation : 1st, distribute 2nd, eliminate redundant parentheses 3rd, add the numbers 4th, combine like terms.

(7x + 4) - (5x + 5) is 2x - 1

explanation : 1st, distribute 2nd, eliminate redundant parentheses 3rd, subtract the numbers 4th, combine like terms.

(2x - 3) + (7x + 11) is 9x + 8

explanation : 1st, eliminate redundant parentheses 2nd, add the numbers 3rd, combine like terms.

(-4x - 5) + 2(3x - 4) is 2x - 13

explanation : 1st, distribute 2nd, eliminate redundant parentheses 3rd, subtract the numbers 4th, combine like terms.

2(6x - 7) - (2x + 3) is 10x - 17

explanation : 1st, distribute 2nd, distribute again 3rd, subtract the numbers 4th, combine like terms.

(5x + 4) - (5x + 12) is -8

explanation: 1st, distribute 2nd, eliminate redundant parentheses 3rd, subtract the numbers 4th, combine like terms.

ALSO REMEMBER YOU ARE SIMPLYFYING

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

2,600 divided by 80 = 32.5

step-by-step explanation:
