Answer:
see explanation
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
4XZ = 144 ( divide both sides by 4 )
XZ = 36 cm
-------------------------------------------------------
Also
= , substitute values
= ( cross- multiply )
16BC = 192 ( divide both sides by 16 )
BC = 12 cm
40 and 60
40 = 20 x 2
60 = 20 x 3
GCF = 20

Answer:
There is no solution to this.
Explanation :
We have a double system of equation to solve. Let x be the big number and let y be the smaller number, such that y < x.
x is equal to twice a smaller number plus 3, which translates into : x = 2y + 3
and x is equal to twice the sum of the smaller number and 1 : x = 2 * (y + 1)
We get this system to solve :
It's either x minus 2y equals 3, or x minus 2y = 2 but it can't be both. No solutions exist because the situation describes two lines that have the same slope and different y-intercepts
