Answer:
0; 3.
Step-by-step explanation:
1) if to substitute x=1 into the given equation, it is possible to calculate the value of 'm':
1-m²-m+1=0; ⇔ m²+m-2=0; ⇒ m₁=-2; m₂=1;
2) if m=-2 and m=1, then the initial equation is:
x²-4x+3=0 or x²-x=0;
3) according to the item 3), the 2d root is:
x₂=3 or x₂=0.
Answer:
26 units.
Step-by-step explanation:
AB + BC + AC = AC + AD + DC + 4
AC is common so
AB + BC = AD + DC + 4
AB + BC - AD - DC = 4
Substituting the given values
AB + 7 - 5 - 6 = 4
AB = 4 - 7 + 5 + 6 = 8
So the perimeter of ABCD
= AB + BC + AD + CD
= 8 + 7 + 5 + 6
= 26.
Answer:

Step-by-step explanation:
Answer:
60%
Step-by-step explanation:
6/10 = .6
.6 x 10 = .60
or you can multiply the fraction by 10 and get 60/100 which is .60
