Answer:
Step-by-step explanation:
Quotient is 1.
Remainder = 27.
Answer:
30
Step-by-step explanation:
10 x 1 (for the free throws)= 10
10 x 2 (for the jump shots)= 20
20+10=30
Answer:
(x+2) ^2 =11
Step-by-step explanation:
x^2+4x=7
To complete the square, take the coefficient of the x term, 4
Then divide by 2, 4/2 =2
Then square it 2^2 =4
Add that to both sides
x^2 +4x+4 = 7+4
The left hand side can be rewritten as (x+b/2) ^2 where b is the coefficient of the x term
(x+2) ^2 =11
Answer:
see explanation
Step-by-step explanation:
Using the product/ difference identity
sinxsiny = 
[ cos(x - y) - cos(x + y) ]
Consider the left side
2sin(
+ α)sin( - α )
= cos[ + α - + α ] - cos [ + α + - α ]
= cos2α - cos
= cos2α - 0
= cos2α = right side , thus proven
