Reversing the clauses of an "if-then" statement only sometimes makes the new statement true, so it isn't true or false. For example, reversing the clauses of "if 1=x, then x=1" makes the new statement true, but reversing the clauses of "if x=2, then |x|=2" doesn't.
7x^2 + 3
7(4)^2 + 3
7(16) + 3
112 + 3
115.
Answer:
AE = 4
Step-by-step explanation:
Use the formula
AE*EC = DE*EB
Since we don't know AE or EC, let AE = x and then EC will = 16 - x. The formula then becomes
x(16 - x) = 8(6)

Getting everything on one side and setting it equal to 0 will allow us to factor for x:

Factoring that gives you that
x = 4 and x = 12. That means that one of those sements has a length of 4 and the other has a length of 12. AE is shorter so it's 4 and EC = 12
Answer:
12 and 6
Step-by-step explanation:
12 x 6=72
Answer:
(1) 23.55mm³
(2) 340.17in³
Step-by-step explanation:
Volume of a cone is: 
'r' - radius
'h' - height
<h3>Cone 1:</h3>
The height of Cone 1 is 10 mm. The Diameter of Cone 1 is 3mm.
Radius is half the Diameter.

The radius is 1.5 mm.

The volume of Cone 1 should be about 23.55mm³.
<h3>Cone 2:</h3>
The height of Cone 2 is 13 in. The Radius of Cone 2 is 5 in.
Using 3.14 as pi:

340.166666667 ≈ 340.17
The volume of Cone 2 should be about 340.17in³.
