Quadrilateral abcd has verticales A (3,6), B(-4,9),C(7,-5),and D(1,1). Quadrilateral JKLM has verticales J(-2,1), K(-9,4), L(2,-10) and M(-4,0). Are the quadrilaterals congruent?

step-by-stp

the correct answer is the section c

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
