Tia says every square is a rhombus, so every rectangle must be a rhombus

False.

Step-by-step explanation:

I'm assuming the question was "True or False?"

On the family tree of quadrilaterals, the rectangle is on the same level as a rhombus so the rectangle is not a rhombus.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

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)
