Answer:
13) 4
14) 7
15) 8
How?
21x+6 = 90 by the alternate exterior angles rule so solve and get 4
11x-2=75 by the Corresponding exteriors angles rule so solve and you get 7
8x-4=60 by the vertical angle rule solve and you get 8
Hope this helps :D
We need to solve for the total amount of money that Bianca has. But we need to consider that the total amount that Roberto has is 11 times as much money as Bianca had.
Roberto's total money is $88.
We assigned "x" variable to represent the amount that Bianca has.
Such as we can right the phrase "11 times as Bianca has" into "11X".
We have the complete expression as 88 = 11X and solving for X value, we need to divide both sides by 11.
88 / 11 = 11x / 11
8 = x
The total amount that Bianca has is $8.
Answer:
Step-by-step explanation:
In 2x/(x^2 - 1)1/2
Apply the property of natural log
ln x^m = m ln(x) move the exponent before ln
ln(m/n)= ln m - ln n
multiply 1/2 inside the terms
Good night from Canada!
Let W be the width in meters
Let L be the length in meters.
L*W=464464
L=2W-33
(2W-33)*W=464464
2W^2-33W=464464
2W^2-33W-464464=0
Use the quadratic formula to solve for the zeros
x=-b√b²-4ac/2a
Sub in b=-33 a=2 and c=-464464 and solve using position and negative values for the √b.
We get:
w=490.225 and w=473.725
Through simple algebra we can figure out that x=490.225 is more accurate when using it with the other equations and solving for the given area.
L=2*490.225-33
L=947.45
947.45*490.225=464463.7
Therefore the length is 947.45m and the width is 490.225m.
Hope this helps!
