Answer:
The answer is: A≈451.93m²
Answer: i think is V=4.29m3
Step-by-step explanation:
Volume of Rectangular Prism:V = lwh
-x + 5y = 8
multiply this equation by 3
-3x + 15y = 24
now add it to the other equation ( elimination)
-3x + 15y = 24
3x + 7y = -2
-----------------------
0x + 22 y = 22
divide each side by 22
y =1
substitute into -x + 5y =8 to find x
-x + 5(1) = 8
-x + 5 = 8
-x =3
divide by -1
x =-3
Answer (-3,1)
Choice A
The perimeter is 166.9 ft.
Convert feet to inches to make it easier to calculate. The formula to find the perimeter is... 2(w+h)
once you get your answer, convert inches back to feet.
The answer to (3x-1)2=5 is x= 7/6
