Answer:
8658 ft.
Step-by-step explanation:
Volume= length*width*height
rectangle= 21*18*13= 4914
triangle= 16*18*13= 3744
4914+3744=8658
Answer:
Isosceles triangle
Step-by-step explanation:
A triangle that contains 2 equal sides but one side different
Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
- x intercepts: (-3,0),(5,0)
- y intercept: (0,-15)
The graph is below.
