Answer:

25

Step-by-step explanation:

8b^2 +2a(4c-b)

Let a = 1/4 b=2 c= -3

8 ( 2)^2 +2(1/4) ( 4*-3 -2)

Parentheses first

8 ( 2)^2 +2(1/4) ( -12 -2)

8 ( 2)^2 +2(1/4) ( -14)

Then exponents

8 ( 4) +2(1/4) ( -14)

Then multiply

32 -7

Subtract

25

CALCULAR O PERÍMETRO DE UM RETANGULO, SABENDO-SE QUE SUA BASE E ALTURA DIFEREM 12 M E QUE ESTA É 1/3 DAQUELA
Ostrovityanka [42]

perimeter =48

18+18+6+6=48

x-12=x/3

Multiply both sides by 3

3x-36=x

3x=x+36

2x=36

x=18

18-12=18/3

6=6

One side 18 another side 6
