the three inside angels need to equal 180, so first find the missing inside angle:

86.5 + 41.4 = 127.9

180-127.9 = 52.1

now that angle and y need to equal 180 degrees

so 180 - 52.1 = 127.9

y = 127.9 degrees

Answer:

12 $r^{5}$ + 28 $r^{4}$ - 60 r³ + 28 r²

Step-by-step explanation:

a(b ± c) = ab ± ac (distributive property)

$a^{m} * a^{n} = a^{m+n}$

2r²(6r³ + 14r² - 30r + 14) = 12  $r^{5}$  + 28  $r^{4}$  - 60 r³ + 28 r²

and with that template in mind.

3 units down, D = -3

4 units to the right, C = -4

f(x) = (x - 4)² - 3
