A) The greatest rectangular area will be the area of a square 10 m on each side, 100 m^2.
b) The new dimensions will be 11 m × 11 m.
.. The new area will be (11 m)^2 = 121 m^2.
c) The area was increased by 121 m^2 -100 m^2 = 21 m^2, or 21%.
d) Yes, and no.
.. If you increase the dimensions by 10%, the area will increase by 21%.
.. (40 m)^2 = 1600 m^2
.. (44 m)^2 = 1936 m^2 = 1.21*(1600 m^2), an increase of 21% over the original.
.. If you increase the dimensions by 1 unit, the area will increase by (2x+1) square units, where x is the side of the original. For x≠10, this is not 21 square units.
.. (41 m)^2 = 1681 m^2 = 1600 m^2 +(2*40 +1) m^2 = 1600 m^2 +81 m^2
Basically, all you have to do is substitue the terms given at the top.
x = -3
y = 6
z = -4
<em>The first one will be set up like this:</em>
(-3) + 6 + (-1) = 2
<em>The second one will be set up like this: </em>
-15 + (- -3) + 6 = -6
<em>The third one will be set up like this:</em>
3(-3) - 2(6) + (-4) = -25
<em>The fourth one will be set up like this:</em>
2(-4) - 3 (6) + 4(-3) = -38
<em>The fifth one will be set up like this: </em>
3 ( -3) + 2 (6) + (-4) = -1
<em>The sixth will be set up like this: </em>
(-3)(-4)
---------- = -1
-2 (6)
<em>The seventh will be set up like this:</em>
2 (6) (-4) - 3 (-3) = -39
Hope this helps! Have a good day/night! c:
2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
