Answer:
When we divide by a negative value, the sign for the inequality changes.
Step-by-step explanation:
2x < -8, to solve we would divide by 2 and receive x < -4. However, in solving -2x < 8, we would divide by negative 2, which would result in x > -4. Clearly, these sequences provide opposite answers and that is a rule to inequalities, that when dividing by a negative number, we must flip the less than/greater than sign.
8x-13
2(4)=8
2(-5)=-10
-10-3=-13
<span>∠S = <span>2x/3</span> + 9
</span>
x+2+x+2x+4=180
x=45
Then,
X=x-6=45-6=39
<span>∠S=2x/3 + 9 = 2(45)/3 +9=30+9=39
</span> ~
thus, ∠X = <span>∠S

Answer:
The side length is 2 cm
Step-by-step explanation:
The volume of a cube is s^3
V = s^3
8 = s^3
Take the cube root of each side
8 ^ 1/3 = s^3 ^ 1/3
2 = s
The side length is 2 cm
