Answer:
The answer is 7(x + 25)
Step-by-step explanation:
The question states 25 push-ups plus x amount of push-ups per day. To find how many push-ups per week, we multiply how many push-ups per day by 7 (a week).
Answer:
The answer is c or x=25
Step-by-step explanation:
Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
Here y=1/2 x=pi/3=60°
y=cosx
1/2=cos60° and cos60°=1/2
so LHS=RHS
so that point is on curve y=cosx
