Answer:
FD = 25.94
Step-by-step explanation:
13x - 16 = 4x + 11 (Tangents drawn from an external point are equal)
13x - 4x = 11 + 16
9x = 27
x = 3
substituting x in 4x + 11,
4(3) + 11
12 + 11
23
ΔFED is a right triangle,
FD² = FE² + DE²
FD² = 12² + 23²
FD² = 144 + 529
FD² = 673
FD = 25.94
Hi there
-(-2a+13)+(-9-2)-(-7a-3)
-(-2a+13)-9a-2-(-7a-3)
Distribute the negative sign
-(-2a+13)-9a-2+-1(-7a-3)
-(-2a+13)+-9a+-2+-1(-7a)+(-1)(-3)
-(-2a+13)+-9a+-2+7a+3
Distribute
2a+-13+-9a+-2+7a+3
Combine like terms
2a+-13+-9a+-2+7a+3
(2a+-9a+7a)+(-13+-2+3)
=-12
Any questions ?
I hope that's help !
