Answer: -6-(-2) is the same as -6+2 because you have to use keep, change, change on the first expression. You are subtracting a negative which means you are adding that number. They both equal -4
Steps:
-6-(-2)
Use keep, change, change to solve because you are subtracting a negative.
-6+2
= -4
All real numbers would be the domain here
Answer:
e = - 6
Step-by-step explanation:
-2(e + 3) = 6
-2e - 6 = 6
- 2e = 6 + 6
- 2e = 12
2e = - 12
e = - 12 : 2
e = - 6
A because the week would be equal to the 3 books he read
A = L * W
A = 44
L = 2W - 3
44 = W(2W - 3)
44 = 2W^2 - 3W
-2W^2 + 3W + 44 = 0
(-2W + 11)(W + 4) = 0
W + 4 = 0
W = -4......not this one because it is negative
-2W + 11 = 0
-2W = -11
W = -11/-2
W = 5.5 <=== width is 5.5 yds
L = 2W - 3
L = 2(5.5) - 3
L = 11 - 3
L = 8 <=== length is 8 yds
