Answer:
y²+6y+9
Step-by-step explanation:
Use FOIL(First, inner, outer, last) to distribute the (y+4)² to get to y²+8y+16. You will then distribute in -2(y+4) to get -2y-8. You will then combine like terms, adding in the +1, to get to your answer.
Answer:8
you just add the numbers up and then that si how u get your answer for your problem u are trying to work out.
a₁₅₇ = 1,088
aₙ = a₁ + d(n-1); where 'd' if common difference
a₁₅₇ = -4 + 7(156)
= -4 + 1092
= 1,088
