Question

simplify (2a+3b+4c),(3a+5a+7c) find the solution​

Answer 1

Answer:

Starting with the second given equation;

3a + 5b + 7c = 30

(2a + 3b + 4c) + (a + 2b + 3c) = 30

35 + (a + 2b + 3c) = 30

a + 2b + 3c = -5______(1)

Now, using the first equation

2a + 3b + 4c = 35

( a + 2b + 3c) + (a + b + c)=35

-5 +(a + b + c)=35 [ using__(1)]

a + b +c=40

Answer 2

$(2a+3b+4c)(2a+3b+4c)\\ 2a(3a+5a+7c) + 3b(3a+5a+7c) +7c(3a+5a+7c) \\ 4a {}^{2} + 12ab + 16ac + {9b}^{2} + 24bc + 16 {c}^{2}$
