Apolygon that has all sides the same measure and all angles the same measure is called what? a. regular polygon b. convex polygon c. irregular polygon d. concave polygon

Regular Polygon

Step-by-step explanation:

This is because:

Convex is when no angles can be over 180 degrees, meaning all points point outward

Irregular means that its interior angles and sides can be any measure

Concave is when at least one interior angle is over 180 degrees

Regular is all side measurements and angle measurements are the same

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
