x^2 - 2x = 146
x^2 - 2x - 146 = 0
See attachment. The quadratic formula is needed in this case.
Answer: 80 cubic centimeters
Step-by-step explanation:
Use the formula: V=
Bh
(B is the area of the pyramid's base)
V=(16)(15)
Multiply: 16 x 15 =240
x 240 = 80
V= 80cubic centimeters
Answer:
if you where trying to draw it straight then yes it is a polygon but if it is supposed to be rounded then no it is not.
Step-by-step explanation:
a plane figure with at least three straight sides and angles, and typically five or more.
Answer:
b=14
Step-by-step explanation:
Add 4b and 8b, which you get 12b. Then you add 11 and 1 which you get 12.
12b + 12 = 180 is the next equation.
Afterwards, you subtract 12 from 180.
12b = 168
Divide 12b from 168.
b = 14
40/100 + 50/100 = 90/100
il lui reste 10/100 ou 21 $
10 % = 21 $
100 % = 210 $
