Cole says that all quadrilaterals are polygons but not all polygons are quadrilaterals is he correct explain������
zepelin [54]
YES, this is correct. All quadrilaterals whether is a trapezoid, parallelogram, rhombus and others, they are all polygons and all they have 4 sides and 4 angles. We know that a polygon is a figure with at least three sides and three angles.

Not all polygons are quadrilateral, this is also correct since some polygons have five or more sides and angles.

If f(x) = -5, then f(-3)=
vitfil [10]

Answer:

f(-3)= <em><u>-</u></em><em><u>5</u></em>

g(4)= <em><u>7</u></em>

Step-by-step explanation:

here f(x)= -5, clearly it's not depending on 'x' ,so it will have same value,for all x

i.e, f(-3) is also -5

and, g(x)=2x-1

to get g(4) put x=4 in <u>2</u><u>x</u><u>-</u><u>1</u>

i.e, (2×4)-1 =7
