Answer:
To get the area of the quadrilateral to do see the 4 sides do all four side 7x7x7x7
7/8 x = 21
7x = 21×8
7x = 168
x = 24
Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
6w=30; divide 30 by 6 to the w by itself; the answer is 5
there must be subtraction of multiplication of each two diagonal,
|G|=[12×2-(-6)×0]
=(24+0)
=24ans
