Answer: False</h3>
Reason:
It should be a^(-3)*a^(-3)=a^(-6) based on the rule a^b*a^c = a^(b+c)
A way to see why the equation a^(-3)+a^(-3)=a^(-6) is false is to pick a number like a = 1 to find that...
a^(-3)+a^(-3)=a^(-6)
1^(-3)+1^(-3)=1^(-6)
1/(1^3) + 1/(1^3) = 1/(1^6)
1/1 + 1/1 = 1/1
1+1 = 1
2 = 1
Which is false, so this shows the original equation is false for a = 1. Therefore it is false in general.

Answer:
Area is 70ft
Step-by-step explanation:
Area of a triangle is A=b × h/ 2 or A=1/2×bh
Let height equal h & base equal b
So,
h=14
b=10
Solve,
A=1/2×14×10
A=1/2×140
A=70
Therefore, the area is 70 feet

Answer:
The answer is Graph X.
- Always start by isolating the variable \color{red}y on the left side of the inequality.
- Change the inequality to equality symbol.
- Graph the boundary line from step 2 in the XY-plane.
- The last step is to shade one side or region of the boundary line.
