Answer:
36=x^2+5x
x^2+5x-36=0
(x+9)(x-4)
x= 4
x= -9
The Answer can be 4 or -9, see which option you have.
Step-by-step explanation:
Answer:
The surface area of the figure is 352 cm².
Step-by-step explanation:
Given:
Length(l) = 12 cm.
Width(w) = 4 cm.
Height(h) = 8 cm.
Now, to find the surface area.
By putting the formula to get the surface area:
Surface area = 2(l×w+w×h+h×l)



Therefore, the surface area of the figure is 352 cm².
Answer:
y=5/2x+3
Step-by-step explanation:
easy. just find the slope and y-int.
slope is y2-y1 and under is x2-x1
Answer:
v = 2034.72 mm³
Step-by-step explanation:
radius = 18mm
height = 6mm
pi = 3.14
v = πr²h/3
v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm² x 2mm
v = 2034.72 mm³
