ANSWER QUICKLY PLZZZZZZ ANSWER QUESTION C​

Answer 1

Answer:

$\boxed{12}$

Step-by-step explanation:

E is 5 more than d

f is 7 less than d

a) e = d + 5

b) f = d - 7

c) plug the values of e and f

$= d + 5 - (d - 7)$

When there is a ( - ) in front of an expression in parentheses, change the sign of each term in the expression

$= d + 5 - d + 7$

Since, two opposites add up to zero , remove them from the expression

$= 5 + 7$

Add the numbers

$= 12$
