Answer:
4t+6
Step-by-step explanation:
To find the perimeter of the rectangle you add the length of the sides.
Perimeter= t+ t+ t+ 3+ t+ 3= <u>4t+6</u>
or
Perimeter=2(t)+ 2(t+3)= 2t+ 2t+ 6= <u>4t+6</u>
Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
