Answer:
Four
Step-by-step explanation:
Let's expand and see how many nonzero terms:
⇒ (x+4)(2x²+3x+9)-3(x³-2x²+7x)=
⇒ 2x³ + 3x² + 9x + 8x² + 12 + 36 - 3x³ + 6 x² - 21 x=
⇒ - x³ + 17x² - 12x + 12
As we see the expression has four nonzero terms

Answer:
D.
Step-by-step explanation:
tan A = 6/7.5 = 0.8
m < A = 38.7 degrees.
Answer:
they all have line of symatry
Step-by-step explanation:
Answer is 59
As there are total of 360 degrees, if we leave 297, 63 remains.
Out of 63, 41 are already separated. So 22 degree remain.
So we get an equation
x - 37 = 22
x = 22 + 37
x = 59
