Answer:
8x^6
Step-by-step explanation:
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.

Answer:
Base: 8cm. Height: 21cm
Step-by-step explanation:
We know that the base of a rectangle is 13 cm. longer than the height and the perimeter is 58 cm. Here is how we would set up the problem:
2x+2(x+13)= 2x + 2x + 26 = 4x + 26 = 58 (now we use the distributive property:
4x + 26 = 58
-26 -26
4x = 32
So, the base is 8 cm.
Now it's time to find the height.
So, we know the base (in total) is 16 cm. Now we do 58-16=42. Now we divide 42 divided by 2 = 21 cm.
