Answer:
Step-by-step explanation:



Set each factors equal to zero.


The x-int is

1/4 (8 + 6z + 12)
------------------------------------------------------------
Combine like terms :
------------------------------------------------------------
1/4 (6z + 20)
------------------------------------------------------------
Apply distributive property :
------------------------------------------------------------
1/4(6z) + 1/4(20)
3/2z + 5
------------------------------------------------------------
Answer: 3/2z + 5
------------------------------------------------------------
Answer:
r = 7.7
Step-by-step explanation:
A = πr²
60π = πr²
r² = 60π/π
r² = 60

r = 7.746
Rounded to tenths:

Answer:
in triangle BCD
relationship between base and hypotenuse is given by cos angle
cos 71=b/h
cos71=BD/BC
cos71=67/x
x=67/cos71=205.8ft.
the length of BC to the nearest tenth of a foot is 206ft.
Flat doesn't change
2 changes with x
y=2x+5
yint is 5
to graph
start at center and go 5 up, that is y intercept
go 1 right and 2 up, that is another point
y=2(2)+5
y=4+5
y=9
