Kathleen says that quadrilaterals have right angles Gray says that quadrilaterals do not have to have right angles explain who is correct

Step-by-step explanation:

Some quadrilaterals do have right angles persay squares rhombus

but when a rhombus is streached creating acute or obtuse angels it still remains a quadrilateral.

all a quadrilateral means is that the shape has 4 sides 4 vertex

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
