Answer:
ae
Step-by-step explanation:
Answer:
84 square feet as law of prism = perimeter of traingle ×length
2/5
0.4/1*10/10=4/10
4/10%2/2=2/5
1)
I:y=3x-4
II:9x-3y=14
substitute y into II:
9x-3*(3x-4)=14
9x-9x+12=14
12=14
this is obviously not equal so there is no solution, the lines are parallel
2)
I:y=4x+6
II:5x-y=6
substitute y into II:
5x-(4x+6)=6
5x-4x-6=6
x=12
substiute x into II:
5*12-y=6
-y=6-60
-y=-54
y=54
the solution is (12,54)
<span>4*(5+3)-(8/4)+3*4
4(8) - (2) + 3 x 4
32 - 2 + 12
30 + 12
42
The answer is 42, I believe.</span>
