Answer:
The other zero for the equation is -10.
Step-by-step explanation:
If the axis of symmetry is -3, then the other zero would be on the opposite side of it.
Find the distance from the first zero to the line of symmetry:
4 + 3 = 7
Find the other point:
-3 - 7 = -10
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1
(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0
X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11
The youngest child is 10
The middle child is 11
The oldest child is 12
Check
=====
10^2 = 100
(8*12) + 4
96 + 4 = 100 So the results have been checked.
Answer: x=3.15
All you do is divide 13.23 by 4.2
Answer:
Step-by-step explanation:
An angle is formed where two or more lines meet. It is measured in degrees. And an angle bisector is a straight line that divides an angle into two equal parts.
Given: <XYZ = 
.
Construction: A bisector of <XYZ.
The construction can be seen in the attached diagram.
