Question

Me ayudan a hacerlas??? ​

Answer 1

a)

8(4) + 4(2) = 32 + 8 = 40

b)

6(2) - 2(5) = 12 - 10 = 2

c)

$4 {(2)}^{2} + 5(2) - 6 = 16 + 10 - 6 = 20$

d)

$2(3) + 3 {(3)}^{2} - 7 = 6 + 27 - 7 = 26$

e)

3(6) - 4(-3) - 12 = 18 + 12 - 12 = 18

f)

-6 + 8(-1) - 10 = -6 - 8 - 10 = -24

g)

3(-5) - 5(2) + 8 = -15 - 10 + 8 = -17

h)

$5 {( - 2)}^{2} + 6( - 2) - 7 = 20 - 12 - 7 = 1$

i)

$- 7( - 3) - 6 {( - 3)}^{2} + 11 = 21 - 54 + 11 = - 22$
