Answer:
2304.8 ft^2
Step-by-step explanation:
The lateral area of one of the pyramid is 21.5 * 13.4 * 4/2 = 576.2
There are 4 of them, so we multiply that by 4 : 576.2 * 4 = 2304.8
Answer:
set the bottom equal to zero and exclude the x value you find when you solve the equation.
Step-by-step explanation:
ADC = DAB
CAD = BDA
Answer: DAB, BDA
Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
I'd suggest getting a Texas Instruments TI-84 plus calculator or use des mos .com scientific
