Answer:
7
Step-by-step explanation:
Using the exact values for
cos45° = 
and tan60° = 
, then
2(cos²45° + tan²60°)
= 2( ( )² + ( )² )
= 2( 
+ 3 ) ← distribute
= 1 + 6
= 7
Answer:
Density = 8g/cm³
Step-by-step explanation:
Density = Mass/Volume
Given the following
Mass = 960g
Volume = 120cm^3
Substitute
Density = 960g/120cm^3
Density = 8g/cm³
7a-1=62
One less= -1
seven times a number= 7 x ?
?= a
answer= 62
