Since we are evaluating, we use PEMDAS so we know the order the operations. Follow PEMDAS:

Original Expression: (-1)8+(-1)7-16-14-(-1)2.

Evaluating: -8-7-16-14+2

-8-7=-15-16=-31-14=-45+2=-43.

The answer is -43 according to PEMDAS.

Find the value of x in the isosceles triangle shown below.
Reptile [31]

Answer:

x=10

Step-by-step explanation:

We can use the Pythagorean theorem to find x

The height meets the base at a right angle

The base is bisected ( cut in half) so the base is 6 the height is 8

a^2 + b^2 = c^2

6^2 + 8^2 = x^2

36+64 = x^2

100 = x^2

Taking the square root of each side

sqrt(100) = sqrt(x^2)

10 = x
