Answer:
B. 4x + 1
Step-by-step explanation:
4x^2 + 21x + 5
= (4x + 1)(x + 5)
Factors of this trinomial are (4x + 1) and (x + 5)
Answer
(4x + 1)

Answer:
=14.92...
14 the maximum number of spheres that Daniel can make from the chunk of clay.
.
Step-by-step explanation:
10^3=1000 in^3
1000/2=500 vol of one congruent chunk.
4/3 * pi * r^3 = vol of a sphere
500/(4/3 * pi * 2^3)
=14.92...
Yo sup??
y=(x+4)(x-2)
to find the x intercept put y=0
0=(x+4)(x-2)
so either x=-4 or x=2
Therefore the graph intersects the x axis at -4 and 2
Lenght of x intercept=|-4-2|=6 units
y=(x+4)(x-2)
=x^2+2x-8
This is an upward opening parabola
To find the coordinates of the vertex we can apply the formula
(-b/2a,-D/4a)
b=2
a=1
D=b^2-4ac
=4-4*1*(-8)
=4+32=36
Vertex=(-2/2*1,-36/4*1)
=(-1,-9)
Hope this helps.
