Answer:
81y^2+36y+4
Step-by-step explanation:
First: 9y^2= 81y
Next: 2^2= 4
Then: 9y times 2= 18
Last: 18 times 2= 36y
(this : ^2 means squared in case you did not know)
Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23
None of these are choices, because in order to make 20ths equal a 45th, it was to end in a 20,40,60,80, or ending in 00.
