Which of the following equations is true? A. 1.8(42.4 - 19.8) = (1.8 × 42.4) + (1.8 × 19.8) B. 1.8(42.4 - 19.8) = (1.8 × 42.4) - (1.8 × 19.8) C. 1.8(42.4 - 19.8) = 44.2 - 21.6 D. 1.8(42.4 - 19.8) = 1.8 - 1.8 × 19.8

The answer is B

Step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
