Answer:
7.31 and 0.685
Step-by-step explanation:
x^2 -8x +5 = 0
use the quadratic formula
- (-8) + √(-8^2 -4(1)(5) / 2(1(
(8 + √(64 -20))/2
(8+√44)/2
8+6.63 / 2
14.63/2= 7.31
+7.31
(8- √44)/2 = 0.685
To get to 86 by only using 10's and 1's you count by 10, 8 times and count by 1, 6 times.
Correct answer:
26 = -13x
X = -2
if you need a false answer, make up any number!

and again sorry it's late :D</span>
