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.
They are terms of an algebraic expression that can be simplified to: 2b+2c
Four times the number of c plus two times the number of d can be expressed mathematically as (4c + 2d). This expression represents a linear combination of the variables c and d, scaled by their respective coefficients. The resulting value depends on the specific values of c and d.

The value of such an expression depends on the values assigned to the variables, in this case, x and c.
(a + 2b)(c + 2d)
ac + 2ad + 2bc + 4bd = a(c + 2d) + 2b(c + 2d) = (a + 2b)(c + 2d) Now expand to confirm your answer: c(a + 2b) + 2d(a + 2b) = ac + 2bc + 2ad + 4bd ≡ ac + 2ad + 2bc + 4bd
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.
ac + 2ad + 2bc + 4bd (ac + 2ad) + (2bc + 4bd) group the figures a(c + 2d) + 2b(c + 2d) remove the common divisors of each set (a + 2b)(c + 2d) take the figures in parentheses as one set, and add the outside figures as the other
I--2a+b=2c+2d II--2a+b=c+2d III--a+2b=3d * Here if we perform (I)-(II), we get, c=0 * Using the c we can prove b=0 using (I)-(III). * Now replace 'b' & 'c' as 0 in (I), then we get a=d. Email me at yash2008gates@gmail.com for any queries. I will be very thankful to receive your queries.

The semi-colon converts a C++ expression into a statement.
int x = 2 * (a + b);
That expression has no answer, simply because it's not a question.
