94 if your using the whole frame the math is 5×7=35 we have 2 sides do times 35 by 2 35×2=70 then we do 1×7=7 for the outside of the game then do 7 times 2 b/c you have 2 sides the do your final side by doing 5×1=5 then times that by 2 and you get 10 .70+14+10=94
Answer:
a
Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .
Answer:
(10x + 8) is the polynomial expression for the perimeter of the blanket.
Step-by-step explanation:
The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.
Now, the perimeter of a rectangle having height h and width w is given by
P = 2h + 2w
⇒ P = 2(2x - 3) + 2(3x + 7)
⇒ P = 4x - 6 + 6x + 14
⇒ P = 10x + 8.
So, this is the polynomial expression for the perimeter of the blanket. (Answer)
