A)24 boards/1 * 47.5 inch/boards * 1 ft/12in = 95 ft.
according to dimensional analysis the answer is 95 ft.
b) 95/8 is approximately 12 so 12 boards are needed.
solution is (x, y ) → (- 1, 4 )
y + 2x = 2 → (1)
y + 4x = 0 → (2)
subtract equation (1) from (2) to eliminate term in y
(y - y ) + (4x - 2x ) = (0 - 2 )
2x = - 2 ( divide both sides by 2 )
x = - 1
substitute x = - 1 in either (1) or (2) and solve for y
(1) → y - 2 = 2 ( add 2 to both sides )
y = 4
solution is (x, y ) → (- 1, 4 )
Step-by-step explanation:
4x-9=15
Solutuon
4x-9=15
4x=15-9
4x=6
x=6:4
x=1,5

hope it help you....
bcoz of in ∆jml and∆jkl
JM=JK(given)
MJ= KJ (given in figure)
and,LJ=LJ (common)
so , criteria 1 is correct sss
