Answer:
x^2 + 14x + 49 = 0
Step-by-step explanation:
Answer:
<h2>2 and three-fourths </h2>
Step-by-step explanation:
Given the expression 
, the equivalent expression can be gotten as shown;
2 and three-fourth therefore gives the required expression
Answer:
choice 1) -6 and choice 2) -5
Step-by-step explanation:
choice 1)
-(1/2)-6)+6 > 8
9 > 8
choice 2)
-(1/2)(-5)+6 > 8
8 1/2 > 8
SA=2H(L+W)+LW for open box
20=2H(4+W)+4(W)
distribute
20=8H+2WH+4W
divide both sides by 2
10=4H+WH+2W
solve for 1 variable, pick W
10-4H=WH+2W
10-4H=W(H+2)
(10-4H)/(H+2)=W
V=LWH
subsitute 4 for V, subsitute H for H and (10-4H)/(H+2) for W
V=(4)(H)(10-4H)/(H+2)
V=(40H-16H²)/(H+2)
find max value
take deritivitive of this thing
V'=-16(H²+4H-5)/((H+2)²)
using sign chart
sign changes from positive to negative at H=1
so at H=1
find W
W=(10-4H)/(H+2)
W=2
the dimeionts are
length=4ft
width=2ft
height=1ft
(the volume is 8 cubic feet)
