Area of a square is side length ^2
To find the length of the side of a square from the area, that’s the square root of the area:
Length of side = sqrt(81) = 9 meters
Area of wall = length of side x height:
Area of wall = 9 x 5 = 45 square meters
Answer: 45 square meters
Are you are saying that the absolute value of negative six times x equals 54? If you are, then the answer is x equals positive or negative 9. To solve, set up two equations, because it is an absolute value question. In the first equation, write -6x=54. Divide by -6 to get -9. That is just one of two answers. In the second equation, write 6x=54. Divide 54 by 6 to get positive 9. Your answer is positive and negative 9.
41, because the ratio is the same
Which equation represents the line that passes through (–8, 11) and (4,7/2 )?
☆☆☆☆☆☆☆☆☆☆☆☆☆☆A. y =-5/8x + 6
B.y =-5/8 x + 16
C. y = -15/2x – 49
D. y =-15/2 x + 71
Circumference of circle = 2 pi r
= 2 x 3.14 x 6
= 6.28 x 6
= 37.68 cm
Area of circle = pi r^2
= 3.14 x 6^2
= 3.14 x 36
= 113.04 cm^2
