Answer 1

Answer:

D. 25

Given:

(0.14 $\times$ 0.14) - (2 × 0.14 $\times$ 5.14) + (5.14 $\times$ 5.14)

Rule used:

Calculation:

(0.14 $\times$ 0.14) - (2 $\times$ 0.14 $\times$ 5.14) + (5.14 $\times$ 5.14)

= 0.0196 - 1.4392 + 26.4196 = 25

∴ The value of (0.14 $\times$ 0.14) - (2 $\times$ 0.14 $\times$ 5.14) + (5.14 $\times$ 5.14) is 25
