1) Resolva a expressão numérica 18 − (−5 − 2 − 3) + 20 − (−6 + 8) − (−1 − 8 + 3) e assinale o seu respectivo resultado. A( ) 14 B( ) 25 C( ) 32 D( ) 52 E( ) n. d.a

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer

the answer to this is:

factor 2x2+16x+24

2x2+16x+24

=2(x+2)(x+6)

answer:

2(x+2)(x+6)

hope this hmu if needed
