Answer:
136 in
Step-by-step explanation:
Assuming the figure is a square with equal sides, then
4x - 2 = 3x + 7 ( subtract 3x from both sides )
x - 2 = 7 ( add 2 to both sides )
x = 9
Thus side = 3x + 7 = 3(9) + 7 = 27 + 7 = 34
Thus
perimeter = 4 × 34 = 136 in

Step-by-step explanation:
Answer:
0, π, 7π/6, 11π/6 on the interval 0 ≤ ø <2π.
Step-by-step explanation:
sinø + 1 = cos2ø
Use the identity cos 2o = 1 - 2 sin^2 o:
sin o + 1 = 1 - 2 sin^2 o
2sin^2 o + sin o + 1 - 1 = 0
2 sin^2 o + sin o = 0
sin o (2 sin 0 + 1) = 0
Therefore sin o = 0 or sin o = -1/2.
For sin o = 0 , o = 0, π radians.
For sin o = - 1/2, o = 7π/6, 11π/6 radians.
Answer:
512
Step-by-step explanation:
1st term =a
common ratio = r
a*r with the exponent n-1
a=4 r=2 n=8
8th term 4*(2 at the seventh power)= 512
OR
1st term :4
2nd term = 4*2=8
3rd term 8*2=16
4th term 12*2=32...............8th term 256*2=512
