Answer:
21.75m
Step-by-step explanation:
14.5×150 =2175cm
1m =100cm
to convert into m divide 2175 by 100
=21.75m
Answer:
the second one
Step-by-step explanation:
we dont know if the sides are congruent but we do know we have one height, one lenght, and one width. we have to find the area of two of each, and thats what the second one is
(4x - 2)(6(2x + 7)) = 0
(4x - 2)(6(2x) + 6(7)) = 0
(4x - 2)(12x + 42) = 0
48x² + 168x - 24x - 84 = 0
48x² + 144x - 84 = 0
x = <u>-144 +/- √(144² - 4(48)(-84))</u>
2(48)
x = <u>-144 +/- √(20,736 - 16,128)</u>
96
x = <u>-144 +/- √(4,608)
</u> 96<u>
</u>x = <u>-144 +/- 67.88</u><u>
</u> 96
x = -1.5 +/- 0.707083
x = -1.5 + 0.707083 x = -1.5 - 0.707083
x = -0.792917 x = -2.207083
