Step-by-step explanation:
Area of the octagon = 2(1+√2)8=309.02 units
Answer:
b ≈ 7.54 cm
Step-by-step explanation:
Pythagorean Theorem
a² + b² = c²
a and b are the sides and c is the hypotenuse
hypotenuse is 11 cm
a side is 8 cm
so
8² + b² = 11²
64 + b² = 121
-64 -64
b² = 57
√b² = √57
b ≈ 7.54 cm ( use ≈ because its rounded so its not exact)
Answer:

Step-by-step explanation:
we know that
The surface area of the triangular prism that will be covered with insulation is equal to the area of the two triangular faces plus the two lateral rectangular faces
so
![SA=2[\frac{1}{2}(15)(15)]+2[(30)(15)]= 1,125\ ft^{2}](https://tex.z-dn.net/?f=SA%3D2%5B%5Cfrac%7B1%7D%7B2%7D%2815%29%2815%29%5D%2B2%5B%2830%29%2815%29%5D%3D%201%2C125%5C%20ft%5E%7B2%7D)

the answer keeps going
Answer:
She is incorrect
Step-by-step explanation:
The fundamental theorem of algebra states that if a polinomial has a degree n, therefore has n roots. To fidn these roots the use of complex number imay be necesary .
For the equation, degree is 3, so there are 3 solutions.
