15a² - 22ab - 5b²
15a² - 25ab + 3ab - 5b²
5a(3a) - 5a(5b) + b(3a) - b(5b)
5a(3a - 5b) + b(3a - 5b)
(5a + b)(3a - 5b)
Answer:
48.7 cube inches
Step-by-step explanation:
Let us assume that the ice cream filled the entire volume of the cone.
Diameter of cone = 4 inches
height of cone = 7 inches
diameter of a sphere of ice cream = 5 inches
Total amount of ice cream = volume of cone + volume of sphere
volume of cone = 

h
r = 
=
= 2 inches
volume of the cone =
x
x
x 7
=
x
x 4 x 7
= 29.3333 cube inches
volume of sphere =


r = 
=
= 2.5 inches
volume of sphere ice cream =
x
x 
=
x
x 
= 19.40 cube inches
So that,
Total amount of ice cream = 29.33 + 19.40
= 48.7 cube inches
B. 8 inches, hope this was right and helped:)
Reflexive pretty much means something relating to itself. The reflexive property of equality simply states that a value is equal to itself. Further, this property states that for all real numbers, so your answer will be (A) x = x.
Answer:

Step-by-step explanation:
<h3>Arithmetic sequence:</h3>

6th term is 14 ⇒ 
a + (6 - 1)d = 14
a + 5d = 14 --------------(I)
14th term is 6 ⇒
a + (14-1)d = 6
a + 13d = 6 ----------------(II)
Subtract equation (II) from equation(I)
(I) a + 5d = 14
(II) a + 13d = 6
<u>- - -</u>
-8d = 8
d = 8 ÷(-8)

Plugin d = -1 in equation (I)
a + 5(-1) = 14
a -5 = 14
a = 14 + 5
20th term:

= 19 - 19
