Answer:
a=1 b = -7 and c = 10
Step-by-step explanation:
z^2-7z+10=0
The quadratic is written in the form
ax^2 +bx+c=0
Letting x become z
az^2 + bz+c =0
a=1 b = -7 and c = 10
Answer:
Interior angle of quadrilateral is 360
Sum of the two known angles 222
The sum of the other two is 360-222=138
Ratio 5:18
A=5/23*138=30
B=18/23*138=108
Step-by-step explanation:
Answer:
-sqrt(5) ≤ x ≤ sqrt(5)
Step-by-step explanation:
x^2-5≤0
Add 5 to each side
x^2-5+5≤0+5
x^2 ≤5
Take the square root of each side, remembering to flip the inequality for the negative sign. Since this is less than we use and in between
sqrt(x^2) ≤ sqrt(5) and sqrt(x^2) ≥ -sqrt(5)
x ≤ sqrt(5) and x ≥- sqrt(5)
-sqrt(5) ≤ x ≤ sqrt(5)
8/5 hope this helps
And I am sorry if it is wrong
