Answer:
The numbers are x = 3 and y = 1. Therefore the value of xy is 3.
Step-by-step explanation:
In order to calculate the numbers we will simplify the equation, this is done bellow:
2*x + x(2^2) + (y*2^3) + (y*2^4) = 42
2*x + 4*x + 8*y + 16*y = 42
6*x + 24*y = 42
We can divide the whole equation by 6, so we have:
x + 4*y = 7
The only possible combination of numbers that are positive and integers that will make the equation valid is x = 3 and y = 1. Therefore he value of xy is 3.
Answer:
∠XMZ = 74°
Step-by-step explanation:
Since the arcs XZ and BC are congruent, then
∠BNC = ∠XMZ ← substitute values
6x - 88 = 3x - 7 ( subtract 3x from both sides )
3x - 88 = - 7 ( add 88 to both sides )
3x = 81 ( divide both sides by 3 )
x = 27
Hence
∠XMZ = 3x - 7 = (3 × 27) - 7 = 81 - 7 = 74°
Answer:
I think that the 3rd and 4th are parallel because if you go to the letters and trace (that's what I did, I'm twelve :D) then they make a triangle, and those triangles are parallel to each other.
there are only 2 possible common tangents to circles A and B can exist
ok done. Thank to me :>
