2x^2 + 10x = 0
we can take out x from both terms and we get:
x(2x + 10) = 0
now either x has to be equal to 0 or 2x + 10 has to be equal to zero in order for equation to be equal to 0.
one solution is x=0 as stated above
other is:
2x + 10 = 0
2x = -10
x = -10/2 = -5
Answers are x=0 and x = -5.
we know that
the ratio of the perimeters is equals to the scale factor
scale factor=5/8
scale factor=measure smaller square/measure larger square
let
smaller square=first square
larger square=second square
area smaller square=[scale factor]²*area larger square
so
area larger square=area smaller square/[scale factor]²
scale factor=5/8
area smaller square=225 m²
area larger square=225/[5/8]²----> 225/(25/64)-- > 225*(64/25)-----
> 576 m²
the answer is
the area of the second square (larger square) is 576
m²

Step-by-step explanation:
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.
