Answer:
Step-by-step explanation:Given f(x)=x-5
f(-1)= -1-5
= -6
f(0)=0-5
= -5
f(1)=1-5
= -4
f(2)=2-5
= -3
f(5)=5-5
=0
f(8)=8-5
= 3
Answer:
A) 2a + 6
Step-by-step explanation:
(5a + 3) + (2a + 3) + x = 9a + 12
Add both side lengths plus the unknown side to equal the perimeter.
7a + 6 + x = 9a + 12
-7a -6 -7a -6 Subtract 7a + 6 on both sides
x = 2a + 6 This is the missing side length.
The factored forms of that is (x + 6) (x - 7).

Answer:11
Step-by-step explanation: Bases of trapezoid : 11 meters and 14 meters
height of trapezoid : 10 meters
Area of trapezoid = (sum of bases / 2) height
A = (11m + 14m)/2 * 10m
A = 25m / 2 * 10m
A = 12.5m * 10m
A = 125m²
