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)
The height of the rectangle is 15 while the base is 3.
15+15+3+3=36cm
Answer: -1
Step-by-step explanation:
because x equals to -2, thus the first term is -2 * -2 = 4.
For the second terms,^3 and the square root canceled, so you got the answer still y, which is also -5. Therefore, you add them. and you got the answer (4) + (-5) = -1
