The expression 3a + b - 7c + 2d represents a mathematical formula involving the variables a, b, c, and d. To find the answer, you need specific numerical values for each variable. Without those values, the expression remains in its algebraic form and cannot be simplified further.
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2

No
Its evaluation is: (4*5)+(7*3) = 41
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
Gathering like terms together, this is equal to 5a + 3b + 7c.
Well I got this: 2c+7=9+6-7c+2c 2c+7=15-9c 11c+7=15 (add 9c) 11c=8 ( Subtract 7) 11---11 ( Divide 11) C=0.72
12c + 2b
To factor out the greatest common factor from the given expression 14cd - 7c, we first identify the common factors of the coefficients and variables. The greatest common factor of 14 and 7 is 7, and the common factor of c is c. Therefore, we can factor out 7c from both terms to get 7c(2d - 1).
7c+4

No
c = 3
Its evaluation is: (4*5)+(7*3) = 41
Oh, dude, that's like super easy. So, 7c plus c is basically just adding up the number of c's, which gives you 8c. It's like math, but with letters instead of numbers. So yeah, 7c plus c equals 8c. Math made fun, right?
12a + 6b + 6c = 6(2a + b + c)
