ABCD is a rectangle. Find the length of each diagonal.
AC = 2(x-3)
BD = x+5
2 answers:
So this is what I did and I god AC=16 and BD=16
AC = 2 (x-3)
BD = x + 5
For this case, the length of the diagonals is the same.
Therefore we have:
AC = BD
Substituting values we have:
2 (x-3) = x + 5
From here, we clear the value of x.
We have then:
2x-6 = x + 5
2x - x = 5 + 6
x = 11
Finally, we substitute the value of x in any of the equations:
11 + 5 = 16
Answer:
the length of each diagonal is:
16 units

Answer: 12b
Step-by-step explanation: you multiply 4 by 3 but keep the b
X⁴-14x²+45=0
(x²) ²-14x²+45=0
let y=x²
y²-14y+45=0
(y-9) (y-5) =0
y=9 or y=5
x²=9 or x²=5
x=±3 or x=±√5
