A^2 -121 = a^2 -11^2 = (a-11)(a+11)
so the second choice is right sure
We know that
[perimeter of rectangle]=2*[length+width]
length=(2x-7)
width=(x²-5)
[perimeter of rectangle]=2*[(2x-7)+(x²-5)]----> 2*[x²+2x-12]---> 2x²+4x-24 in
the answer is
(2x²+4x-24) in
The common difference is -5
right now, a₁₂ = 22
to get a₁, subtract 5 each time you subtract one from the subscript
so
a₁₁ = 17
a₁₀ = 12
a₉ = 7
a₈ = 2
a₇ = -3
a₆ = -8
a₅ = -13
a₄ = -18
a₃ = -23
a₂ = - 28
a₁ = -33
a₁ = -33
hope this helps

Answer: Option D, 16/21
Answer:
8x + 3
Step-by-step explanation:
The cost of 5 t-shirts and 3 skirts
= 5(x - 3) + 3(x + 6)
= 5x - 15 + 3x + 18
= (5x + 3x) + (-15 + 18)
= 8x + 3
