90=B

91=B

92=A

Answer 2

Answer:

89) option c

90) option a

91) option b

92) option a.

Step-by-step explanation:

➡89.

Diagonal = √(length) ^2 + (width)^2

Diagonal = √16 + 9

Diagonal= √25

Diagonal= 5 cm.

➡90.

Upper limit is 200.

➡91.

x^b+a * x^b + c * x^c +a/ (x^a * x^b * x^c)^2

= x^ (b + a + b + c + c + a) / { x^(a + b+ c)}^2

= x^2(a + b + c) / {x^(a + b+ c)}^2

= x^2(a + b + c) / x^2(a + b + c)

= 1.

➡92.
