Answer:
Length = 20 feet; x = 14
Step-by-step explanation:
Parameter = width + length + width + length
64 feet = 12 feet × 2 + (x + 6) feet × 2
64 = 24 + (x + 6) × 2
64 - 24 = (x + 6) × 2
40 = (x + 6) × 2
40 ÷ 2 = x + 6
20 = x + 6
20 = length
20 - 6 = x
14 = x
Answer:
-15
Step-by-step explanation:
-3+-2*5-2=-15
Hi there!
![\large\boxed{f^{-1}(x) = \sqrt[3]{\frac{x+4}{9} } }](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Bf%5E%7B-1%7D%28x%29%20%3D%20%20%5Csqrt%5B3%5D%7B%5Cfrac%7Bx%2B4%7D%7B9%7D%20%7D%20%7D)
Find the inverse by replacing f(x) with y and swapping the x and y variables:
Isolate y by adding 4 to both sides:
Divide both sides by 9:
Take the cube root of both sides:

Answer:
Step-by-step explanation:
Corresponding angles: ∠2=∠ 6 ; ∠1 = ∠5 ; ∠4 = ∠8; ∠3 =∠7
Vertically opposite angles: ∠1 = ∠3; ∠2 = 4; ∠5 = ∠7 ; ∠6 = ∠8
Interior angles : ∠4, ∠3 , ∠6, ∠7
alternate interior angles are equal: ∠3 = ∠5 ; ∠4 = ∠6
