Answer:
To solve this equation we need to get x by itself.
4x-6=10x-3, (the first step would be adding 6 to both sides.)
4x=10x+3 (the next step is the subtract ten from both sides.)
-6x=3 (Last step is the divide both sides by -6.)
x=-1/2

Answer:
3.6 cm
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2)*h
We know the area of 4.5 and the top is 1 and the bottom is 1.5
4.5 = 1/2 (1+1.5) h
4.5 = 1/2 (2.5) h
4.5 =1.25h
Divide each side by 1.25
4.5/1.25 = 1.25h/1.25
3.6 =h
Use the commutative property to reorder the terms
2x-29x-132=0
Next step
Collect like terms
-27x-132=0
Move the constant to the right-hand side and change its sign
-27x=132
Divide both sides of the equation by

Answer:
20 sides
Step-by-step explanation:
The formula that relates interior angles with number of sides is:
Where
n is the number of sides.
We know each interior is 162 degrees, so we substitute and cross multiply and solve for n:
THus, the polygon has 20 sides
