Add the following decimals. a. 0.654 + 0.45 b. 0.9 + 0.3 c. 0.004 + 0.8342 d. 0.98 + 0.245 e. 0.04 + 0.8532 f. 0.57 + 0.436 + 0.4321 g. 1.54 + 45.6 + 32.78 h. 35.78 + 0.6 + 4.3 + 4.893

a. 1.104 , b. 1.2 , c. 0.8382 , d. 1.225 , e. 0.8932 , f. 1.4381 , g. 79.92 , h. 45.573

Step-by-step explanation:

In order to add decimal numbers, first we convert unlike decimals into like decimals i.e decimal numbers having same no. of digits on right side of decimal.

a.

b.

c.

d.

e.

f.

g.

h.

i do not know this sorry : (

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
