Someone help this question is hard and really not easy please help

51

it says UVW congruent to EFC

each letter here shows you where they match

u and e matches

v and f matches

w and c matches

look for the order they put the letters and they will match their corners

they are asking for FEC

the middle letter tells you the corner they are looking for, which is corner E

since E and U match, E must be 51 ° just like U

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)
