Question

find the product of (-18)×(5)×(-4)×3 =​

Answer 1

Answer:

(16)1080

(17)2/5

(18)45 degrees

(19)-4800

(20)7/12

Step-by-step explanation:

(16).

(-18)*(5)*(-4)*(3)

= (-90)*(-12)

= 1080

(17).

3/5 - 1/5

= (3-1)/5

= 2/5

(18).

Let first angle be x degrees, then second angle will also be x degrees since both are equal,

Since they are complementary to each other,

therefore,

x + x = 90

2x = 90

x = 90/2

x = 45 degrees

(19).

75*(-48)+25*(-48)

= (-48)*(75+25)

= (-48)*(100)

= -4800

(20).

1/4 + 1/3

= (4 + 3)/12

= 7/12

Hope this helps
