Simplifying √196 before doing the multiplication:
( √196 ÷ 7 ) × √48
= ( (√4 × √49) ÷ 7 ) × √48
= ( (2 × 7) ÷ 7 ) × √48
= 2√48
Simplifying √48:
= 2 × √16 × √3
= 2 × 4 × √3
= 8√3
which is irrational because it's a square root
It would be negative seeing the key word is down. (:
Hope I could help!
Because December is really cold
20t +15t+90+25t-75=60t+15
60t+15/3=20t+5 as the average
