Answer: x=-2
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
Hope this helps you out.
Answer:
( P -2w) /2 = l
Step-by-step explanation:
P= 2W + 2l
Subtract 2W from each side
P= 2W -2W + 2l
P -2W = 2l
Divide by 2
( P -2w) /2 = l
<span>Each Exterior Angle = (360 degrees) ÷ (Number of Sides)
Each Interior Angle = 180 - (360 / Number of Sides)
Therefore, since one angle is 4 times the other then,
</span>
4 * (360 degrees) / (Number of Sides) = <span>180 - (360 / Number of Sides)
Number of sides = 10 (it is a decagon)

3. =1260
Step-by-step explanation:
3.= 9×(32+108)
= 9×140
= 1260 .
6(3m + -5n + 7)
Distribute the 6.
6*3m + 6*-5n + 6*7
Simplify each individual term.
18m -30n + 42
