Answer 1

Answer:

Use the identity a^2+b^2+2ab=(a+b)^2

Step-by-step explanation:

(3.7)^2+(2.3)^2+2(3.7)(2.3)

= (3.7+2.3)^2

=6^2

=36 Numerator

Denominator

4.6×4.6 - 3.4×3.4

a^2-b^2= (a-b)(a+b)

(4.6-3.4)(4.6+3.4)

= 1.2× 8

= 9.6 Denominator

= 36/9.6

= 360/96

= 3 whole 3 by 4

Option (a) is right
