Wewaii [24]

Answer:

D. 11.6 cm

Step-by-step explanation:

The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:

c^2 - b^2 = a^2

Where,

a = x cm

b = 11 cm

c = 16 cm

Thus:

16^2 - 11^2 = x^2

256 - 121 = x^2

135 = x^2

\sqrt{135} = \sqrt{x^2}

\sqrt{135} = x

11.61895 = x

x = 11.6 cm (nearest tenth)

-6(a + 8)<br> I need help!
Yuliya22 [10]

Answer: I got -6a + 48

Step-by-step explanation:I distributed and I got negative 6a because when you distributed the variable goes with whatever number is before it and I got 48 because -6 multiplied by 8 you get positive 48 because the 8 is bigger then the negative 6 so I don't know if your teacher wants you to solve for the answer but like I said I got -6a + 48
