Answer:
18 cm
Step-by-step explanation:
The perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Fill in the given information and solve for the width.
90 = 2(27 +W)
45 = 27 +W . . . . . divide by 2
18 = W . . . . . . . . . subtract 27
The width of the rectangle is 18 cm.
Creative use of formatting may make this problem clearer to me, to other helpers and perhaps to you as well. As typed, your
31y^3
Sqrt31y^3/9x^6 seems to indicate Sqrt( ----------- )
x^6
31y³
or √( ---------- )
x^6
√31 cannot be reduced.
√(y³) = y√y.
√(x^6) = x³
Putting this all together, we get the final answer
√31*y*√³
( --------------- )
x³
Answer: A and C because you plug in the numbers -6 for x and -1 for y and check each one.
Hope this helps :)
Y=1/3(x+(3*(-60))) => y=1/3(x-180)
Answer:
x = 4
Step-by-step explanation:
<2 and <6 are equal because of the corresponding angles thm so:
4x + 44 = 6x + 36
4x - 6x = 36 - 44
-2x = -8
x = 4
