Hope this helps you
Step-by-step explanation:
43. A "Square" cornfield, which means all 4 sides has the same lenght BxH
164.000 ft^2=404.96 NO
156.816 ft^2=396 Yes
174724 ft^2=418 Yes
215908 ft^2=464.66 NO
44. it's the same here, if the area is 81. then each side of the square is 9
1st figure: it has 12 sides x9 =108
2nd figure: it has 10 sides x9=90
3rd figure: has also 12 sides x9=108
45. 13^3= 13x13x13 = 2197
46. 25^2= 25x25 = 625
47. 15^3= 15x15x15 = 3375
48. 34^2= 34x34 = 1156
49. 5 root121= 5 (11)=55
50. -6.root36= - 6 (6)= -36
51. 10 root3 (8) = 10(2) = 20
52. -4. root 144= -4(12) = -48
Answer: Rewrite using additve inverse:. 7 +(-8)
The number line: ) A horizontal number line is shown with labels from negative 8 to positive 8
A red arrow begins at 7 and ends at negative 1
Explanation: Additive inverse means reverse the sign from positive to negative, or from negative to positive and add.

x – 2y = -2
x – 4y = 10 => x = 10 + 4y
_________
10 + 4y - 2y = -2
2y = -12
y = -12/2
y = -6 => x = 10 + 4y = 10 + 4*(-6) = 10 - 24 = -14
