Answer:
The first one:
−8x4−14x2−3
Step-by-step explanation:
(-4•2-1)(2•2+3)
-4•2 = -8
-8 - 1 = -9
(-9)(2•2+3)
2•2 = 4
4+3 = 7
(-9)(7) = -63
Now we find the one that equals -63:
-8•4-14•2-3
(-8•4)-14•2-3
-32-14•2-3
-32-(14•2)-3
-32-28-3
(-32-28)-3
-60-3
-60-3 = -63
BAM! THE ANSWER!
Answer:
55.95 ft²
Step-by-step explanation:
Circumference formula: C = 2πr => r = C / (2π)
Area formula: A = πr²
Substituting C / (2π) for r in the above equation, we get:
C 47 ft
A = π( ----------- )² = π ( -------------- )²
2π (2π)
or ...
π(47 ft)² 2209 ft²
A = ---------------------- = -------------------- = 55.95 ft²
4π² 4(3.14159)²
