Answer:

B. $33.7 mm; 54mm^2$

Step-by-step explanation:

To find the perimeter, use the formula:

P = a + b + c

P = 12 + 12 + 9.7

P = 33.7

To find area, use the formula:

A = $\frac{1}{2} bh$

A = $\frac{1}{2} (12)(9)$

A = $\frac{1}{2} (108)$

A = 54

WHATS THE ANSWER PELASE SOMEONE HELP

Travka [436]

Answer:

Step-by-step explanation:

Take a look at the graph starting from the left. You’ll see that on the horizontal line, the graph starts at -4 then starts to go downward until it gets to -2 and it starts going up after that so your first interval is (-4, -2). The line increases from -2 to 2 and then it starts sliding downward again from 2 to 4 so your second decreasing interval is (2, 4).
