Answer:
4x^3 − 16x^2 − 12x − 40
Step-by-step explanation:
= 4(x)(x^2 +x +2) +4(-5)(x^2 +x +2) . . . use the distributive property
= 4x^3 +4x^2 +8x -20x^2 -20x -40 . . . . and again
= 4x^3 -16x^2 -12x -40
72
Using property :
Tangent drawn from same point are equal in length , we have
JA=JB ,
AL=AC,
CK=KB
hence perimeter = JA+JB+AL+AC+CK+KB=72 units
End answer is five hundred and 6
Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
Answer:
3 4/8 or 3 1/2
Step-by-step explanation:
First thing you would have to do is making, 8 1/2, the denominator 8. so what is 4 x 2? 8. So then you would have to multiply the 1 by 4 and you would get 8 4/8. Subtract 8 1/2 and 5 7/8 and you get 3 4/8. Simplify and you would get 3 1/2
