12 inches

if the length = x,

P = 150 inches

=2 { ( 5x + 3 ) + x }

=10x + 6 + 2x

=12x + 6

Therefore 12x + 6 = 150

12x = 150 - 6

12x = 144

x = 12

Please help due ASAP <br> Show workings please
Nostrana [21]

Step-by-step explanation:

I don't know if this is the right way to so it, but I would do it like this

since a triangle has 180 degrees, the angles all have to add up to 180

So 180 = a + b + c

we already know a, its 95

So 180 = 95 + b + c

now we know the equation for b, so we'll just put it there instead of the b, and since the angles are the same, we should put it instead of c too

180 = 95 + (4x-15) + (4x-15)

now subtract 95 from both sides

85 = (4x-15) + (4x-15)

add the xs and numbers together

85 = 8x - 30

now add the 30 to both sides

115 = 8x

divide by 8

your x is 14 3/8 or 14.375 or 115/8

that's not your angle, that's your x

Answer: D. 7^11

Step-by-step explanation:

For exponents with the same base, we just add the exponents and keep the same base. 7 is the same base; therefore 5+6=11 which means the answer is 7^11

I am Lyosha [343]
Assuming that the equation is 4.7x+3.8=13.2:
 4.7x=9.4 - isolate x on one side
x=2 - divide 9.4/4.7 to solve for x
The answer is C.
