Step-by-step explanation:
1. x² = V12²+16²
= V144+256
= V400
x² = 20
2. x² = V14²-11²
= V196-121
= V75
x = V25×3
= 5V3
3. x² = V9²-7²
= V81-49
= V32
x = V16×2
= 4V2
Answer:
the third one
Step-by-step explanation:
Answer:
-2.1x +14.4y
Step-by-step explanation:
Use the distributive property to eliminate parentheses. Then combine like terms.
(12.7y-3.1x)+5.9y-(4.2y-x)
= 12.7y -3.1x +5.9y -4.2y +x
= x(-3.1 +1) +y(12.7 +5.9 -4.2)
= -2.1x +14.4y
is between
and
, i.e. between 4 and 5,
