Answer:
x = 9
Step-by-step explanation:
Create an equation:
x = some number
and = add
other number = -15
x + (-15) = -6
remove () using rule
x - 15 = -6
add +15 to both sides
x = 9
Here is your answer
1. (−2^2 − 4 + 13) + (12^2 + 2 − 25)
= (4-4+13)+ (144+2-25)
[Note:- -2^2=(-2×-2)= +4]
= 13+ (146-25)
=13+121
= 134
2. (7^2 + 4 − 26) − (−7^2 − 3 + 15)
= (49+4-26) - (49-3+15)
= 49 +4 -26 -49 +3 -15
= 7-41
= -34

Answer:
273.2
Step-by-step explanation:
Surface area of the pyramid=Area of square+4*area of triangle
Surface area of the pyramid=10^2+2*(8.66)*10
Surface area of the pyramid=100+173.2=273.2
