Answer:
144.
The reason is because 1 ft = 12 in, (1 ft)2 = (12 in)2 = 144 in2.
Step-by-step explanation:
The first one will be:
7x^6 - 7x^5 +28x - 4x² - 60
And the second:
-9x⁴-3x²-4x²+5x
Answer:
-1836
Step-by-step explanation:
(-13) × (-17) = 221
(-187) × 11 = -2057
• Add 221 to -2057 (Different sign '-' , '+' subtract)
-1836 (Bigger number contains which sign is the sign of answer:::::2057 is greater than 221 ; it contains '-')
The right triangle with angle 45 ° has adjacent leg 9 feet
So the opposite leg is calculated from
tan 45 = opposite leg / adjacent leg ⇒ adjacent leg = 9 tan 45 = 9.
That is the distance bc.
The right triangle with angle 60° has adjacent leg 9 and opposite leg (x+9), where x is the distance ab.
Then tan(60) = (x+9) / 9 ⇒x+9 = 9 tan(60)
x + 9 = 15.59
x = 15.59 - 9 = 6.59
Answer: 6.59 feet
