Add them together
AC+CE= EA
24+13= 37
x - shortest side
2x - second side
x + 26 - third side
174 ft - perimeter
x + 2x + (x + 26) = 174
4x + 26 = 174 |-26
4x = 148 |:4
x = 37 ft
2x = 2(37) = 74 ft
x + 26 = 37 + 26 = 63 ft
Answer: 37 ft, 74 ft and 63 ft.
Answer:
In BOLD.
Step-by-step explanation:
f(x) = (x - 1)(x + 7)
Convert to vertex form.
= x^2 + 6x - 7
= (x + 3)^2 - 9 - 7
= (x = 3)^2 - 16
So the vertex is at (-3, -16)
Also, as the vertex is a minimum the graph is increasing on interval x > -3.
From the graph we see:
The graph is positive on the interval
where x < -7 and x > 1.
- and negative where
-7 < x < 1.
Answer:
x=11
Step-by-step explanation:
5x = 55
Divide each side by 5
5x/5 = 55/5
x = 11
