Answer:
father = 32 s = 5 y/o
Step-by-step explanation:
f s = 160 ====> s = 160/f
f+4 = 4 ( s+4)
f + 4 = 4 (160/f +4)
f + 4 = 640/f + 16
f^2 + 4f = 640 + 16 f
f^2 -12f - 640 = 0 Use Quadratic formula to find f = 32 then s = 5
Answer:
the value is whatever the greatest number u have
Step-by-step explanation:
if ur greatest number is there
Answer:
Part A :
Area = π*r² = π(d/2)² = π*(8/2)² =
π*4² = π*16 square inches
Part B:
d=8+4 = 12 and r = d/2 = 6 inches
We know :
Area = π*r²
Area = π*6²
=36π

x - 9 = 11
+9 +9
x = 20
Answer: 3x^3 - 3x^2 - 4x - 4
Explanation:
(x - 2)(3x^2 + 3x + 2)
= x(3x^2 + 3x + 2) - 2(3x^2 + 3x + 2)
= 3x^3 + 3x^2 + 2x - 6x^2 - 6x - 4
= 3x^3 - 3x^2 - 4x - 4
