Step-by-step explanation:
Answer:
y = 10.36
Step-by-step explanation:
y - 1.6 = 8.76
add 1.6 to both sides
y - 1.6 + 1.6 = 8.76 + 1.6
y = 10.36
Answer:

Step-by-step explanation:
Given equation:

Factor out 3 from the first 2 terms:

Divide the coefficient of x by 2 and square it: (-3 ÷ 2)² = 9/4
Add this inside the parentheses and subtract the distributed value of it outside the parentheses:

Factor the parentheses and combine the constants:

Answer:
26.2 units
Step-by-step explanation:
We are given the points/vertices
A(6, 3),
B(6, - 2) , and
C(- 4, 3)
Step two
Let us find the distances between the given points/vertices
A-B =A(6, 3) to B(6,-2)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((6-6)²+(-2-3)²)
d=√(-2-3)²)
d=√(-5)²)
d=5 units
B-C=B(6, - 2) to C(-4, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((-4-6)²+(3+2)²)
d=√(-10)²+(5)²)
d=√100+25
d=√125
d=11.2 units
C-A=C(-4, 3) to A(6, 3)
d=√((x2-x1)²+(y2-y1)²)
Substitute
d=√((6+4)²+(3-3)²)
d=√(10)²
d=√100
d=10 units
Hence the perimeter is 5+11.2+10
P=26.2 units
a and c i think
the blue circle is all the people who had brothers one name was in the blue circle so one person had a brother but the in between part of the too circles are who had both a brother and a sister so the is one name in the between purple so you count that one to for brother and for sisters
there were 2 people that had brother
and four people that had sisters
and one that had both
