Help pls!! Which scale factor was used to transform triangle MNP to triangle RST?

Step by step explanation:

Here two triangles are given to us . The two triangles are ∆MNP and ∆RST. They are similar to each other . That is ,

Now we know that the corresponding sides of the similar triangles are proportional . Hence here ,

Here we are given the value of side NP as 7 and ST as 2 . So here we can find out the scale factor by dividing these two .

what are you trying to solve here

step-by-step explanation:

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)
