Hope this helps!
Rectangle diagonals are equal.
2(5a+1) = 2(a+1)
10a + 2 = 2a + 2
10a -2a = 2 - 2
8a = 0
⇒ a = 0
AC = 2(5a+1) = 2(5 × 0 +1)= 2(0 + 1) = 2 × 1 = 2 <span>
</span>BD = 2(a+1) = 2(0 + 1) = 2 <span>× 1 = 2
</span>
Ansver: AC = BD = 2
Answer is x= 3 or x= -2
x(x+2) -3 (x+2) = 0
(x+2) (x-3) =0
x+2=0
x-3=0
so..
x=-2
x=3
hope this helped a bit good luck :)
