Answer:
1. x = 0, 4, -9
2. x = 3, 3, -5
3. 2x^3 - 9x^2 + 7x + 6
4. x = -6, -8, -15
5. 2x^3+10x^2+12x
Factor out the common factor:
2x (x^2+5x+6 )
Factor what's left in parentheses:
2x (x + 2) (x + 3)
6. x = 0, 4, -9

Answer:
Step-by-step explanation:
Pretty Tall.
Tan(72) = opposite / adjacent
The opposite is the height of the building
The adjacent = 100
Tan 72 = 3.077
Tan (72) = opposite / 100
3.077 = opposite / 100 Multiply by 100
3.077 * 100 = opposite
opposite = 307.7
opposite rounded = 308
Okay, so how to do it, so the parentheses around the two doesn’t matter, you can times 4.16 and .2 together to get .832, it is fairly easily.
How I got it: 4.16 is on the top of .2, the decimals line up, you add a zero behind the 2 to make it a 20, now you just Times 4.16 by .20 to get .832
