Hey the answer is 4000 ft^3 , choice c
12x+8 = 2(5x+6)
12x+8 = 10x+12
12x-10x = 12-8
2x = 4
x = 2
then DE = 5x+6 = 5(2)+6 = 16
Answer:
-1/4
Step-by-step explanation:
The slope-intercept form is y
=
m
x+b
,
where m is the slope and b is the y-intercept.
y
=
m
x
+
b
Using the slope-intercept form, the slope is 4.
4 m
=

The equation of a perpendicular line to
y
=

<span>78.6 is a decimal number, you must name it with the whole part first and then the decimal part as part of tenths, hundredths or what it corresponds. In this case the whole part is 78 and the decimal part is 6/10 which is 6 tenths. Then, the number in words is sevety eight and six tenths.</span>
Answer:
Length of XM is 5.5 units.
Step-by-step explanation:
Given △XYZ where MZ is the angle bisector of ∠YZX . we have to find the length of XM.
A triangle with vertices X, Y, and Z. Side XZ is base. A line segment drawn from Z to M bisects ∠YZX into two parts ∠YZM and ∠XZM.
YZ=7 units, XZ=11 units and YM=3.5 units
By angle bisector theorem which states that an angle bisector of an angle divides the opposite side in two segments that are proportional to the another two sides of the triangle.
Hence, 
⇒ 
⇒ MX=5.5 units.
Hence, length of XM is 5.5 units.
