Answer:
∠abc=34°
∠dbc= 44°
Step-by-step explanation:
(5x+4)+(5x-6)=78
10x-2=78
10x=78+2
10x=80
x=8
put x in each equation
∠abc= 5x8-6
40-6
34°
78-34= ∠dbc
∠dbc= 44°
Answer:
The quadratic equation that best models the volume of the box (in terms of W) is:
Step-by-step explanation:
The perimeter of the rectangular base = 28cm
Perimeter of a rectangle = 2(L+W)
2(L+W)=28
L+W=14
L=14-W
Volume of the Box= LWH
Since L=14-W and Height Of the Box= 5cm
Volume of the Box= (14-W)W X 5

G(-8) = (-8+2)/3
g(-8) = -6/3
g(-8) = -2
