Total divided by number of rows=number per row
63/7=9
9 per row
Answer:
(u+2)(2a+9)
Step-by-step explanation:
2a(u+2)+9(u+2)
Taking (u+2) common
We get
(u+2)(2a+9)
Answer:
x=10
Step-by-step explanation:
5.4=0.3x+2.4
5.4-2.4=0.3x
3=0.3x
Dividing both sides by 0.3
x=10
Answer:
the first one
Step-by-step explanation:
Hi, We know:
Sin(a + b) = 2.Sin(a).Sin(b)
Then,
= 2Sin(a).Cos(b)/Cos(a).Cos(b)
Canceling Cos(b)
= 2Sin(a)/Cos(a)
As Tan(a) = Sin(a)/Cos(a)
Then we will stay:
= 2Tan(a)
Or
= Tan(a) + Tan(a)
There is anything wrong on the alternatives
