Question

(1.1× 2.7 y ) (1.1 x- 2.7 y )​

Answer 1

Answer:

$(1.1 \times 2.7y)(1.1 \times 2.7y) = (1.1 \times 2.7y) {}^{2} = >$

$= > ( \frac{11}{10} \times \frac{27}{10}y ) {}^{2}$

$= > ( \frac{297y}{100} ) {}^{2} = \frac{88209y {}^{2} }{10000} = 8.8209 {y}^{2} \: \: ans...$

Answer 2

Step-by-step explanation:

(1.1x+2.7y)(1.1x-2.7y)

= (1.1x)^2 - (2.7y)^2

= 1.21x^2 - 7.29y^2
