Answer:
PT=19
Step-by-step explanation:
It is given that, T is the midpoint of PQ. If T is mid point, then it will bisect the line segment i.e.
PT=TQ
4x + 7=8x - 5
Subtracting 7 both sides
4x + 7-7=8x - 5-7
4x=8x-12
Subtracting 8x both sides
4x-8x=8x-12-8x
-4x=-12
4x=12
x=3
The value of x is 3.
Now,
PT = 4x + 7
= 4(3) + 7
=12+7
=19
Therefore, the length of PT is 19.
Answer:
x = -5
Explanation:
4(2x + 10) = 0
[ Simplify both sides of the equation ]
4(2x + 10) = 0
(4)(2x) + (4)(10) = 0 [Distribute]
8x + 40 = 0
[ Subtract 40 from both sides ]
8x + 40 − 40 = 0 − 40
8x = −40
[ Divide both sides by 8 ]
8x / 8 = −40 / 8
x = -5
Answer:
D
Step-by-step explanation:
Volume of a cylinder is equal to the area of the base circle times the height of the cylinder.
The area of your base circle is 
where r=15 and they are using 
as 3.14.
So we have the area of your base circle is 
inches squared.
Now to find the volume of a cylinder again you just multiply your base area by your cylinder and you get:
cubic inches
Answer:
6(4x + 3y)
Step-by-step explanation:
24 and 18 are both evenly divisible by 6, and so we have
6(4x + 3y)
Answer:
8
- 6r
Step-by-step explanation:
2r(4r^2-3)
= 8 - 6r
