You know x, so just plug it in for the answers. Like AB = x + 7, so since x is 3, then AB is 3 + 7 = 10
BD is 2x + 3x -1 = 6 + 9 - 1 = 14
CE is 3x - 1+ 2x + 3 = 9-1+6+3= 17
44.6 is the answer, but the estimate is 45 since you round up from .5+
6x-5y=9.....
Slope = 2.400/2.000 = 1.200
x-intercept = 9/6 = 3/2 = 1.50000
y-intercept = 9/-5 = -1.80000
So -18+1.8b=-27
Slope = 10
x-intercept = 15/10 = 3/2 = 1.50000
b-intercept = 15/-1 = -15.00000
Answer:
14√2
Step-by-step explanation:
A square with a diagonal automatically makes a 45 45 90 triangle (angles) meaning that the two legs are x and the hypotenuse (diagonal) is x√2
If 14 = x then the diagonal is 14√2
You could also solve with the pythagorean theorem
a^2 + b^2 = c^2 so in this case
14^2 + 14^2 = c^2
196 + 196 = c^2
392 = c^2
√392 = √c^2 the 392 is divisable by 196 so you can divide that out as 14
14√2 = c
50 divided by 8 = 6.25
1oz perfume = $6.25
110 divided by 17 = 6.4705
1oz perfume = $6.4705
Therefore the second option is cheaper
