Answer:
Quadratic Function
Step-by-step explanation:
3x(x-1) -(3x+7)
First, you need to simplify by multiplying what's outside the parenthesis with what's inside.
3x(x) - 3x
3x²-3x = -3x-7
this would become 3x²-6x-7

I plugged in a minus first thats how i got the error then replaced it for a negative <3 hope i coukd be of help
Answer: 55.5 (A.)
Step-by-step explanation:
Since angle A = 29 and angle B = 41, angle C must be equal to 110
180 = m<A + m<B + m<C
180 = 29 +41 + m<C
180 = 70 + m<C
110 = m<C
Therefore, side c must be the longest, side b must be the second longest, and side a must be the shortest.
Since side length a, angle A, and angle B are known, one can use the law of sines to solve for side b.
Law of Sines: sinA/a = sinB/b = sinC/c
sinA/a = sinB/b
sin29/41 = sin41/b
b(sin29/41) = sin41
b = 41(sin41)/(sin29)
b = 55.48
b = 55.5
