Answer:
r = -1/3 and r = 3/5
Step-by-step explanation:
Given the expression 15r^2-6r-3 = -2r
collect the like terms
15r^2-6r+2r-3 = 0
15r^2-4r-3 = 0
Factorize
15r^2-9r+5r-3 = 0
3r(5r-3)+1(5r-3) = 0
(3r+1)(5r-3) = 0
3r+1 = 0 and 5r-3 = 0
3r = -1 and 5r = 3
r = -1/3 and r = 3/5
1. EFG
2. F
3. FA and FB Take a moment to look at this one. The two rays are pointing in opposite directions. They are 180o apart. They share a common point at F.
FE and FG does the same thing.
4. No G is on a line that has only one point on the plane and that point is F.
5, AC has an infinite number of points on the plane.
Volume of a square pyramid = a^2 h/3 Where a= base length = 16 ft for this pyramid and h= 15
16^2 * 15/3 = 768 ft^3
Answer:
Step-by-step explanation:
You need to subtract the coefficients to get the answer.
Let's look at the equation...
The coefficient is 3 and 1
So, you do 3-1
You get 2
So...
