Check the picture below.
the triangle has that base and that height, recall that A = 1/2 bh.
now as for the perimeter, you can pretty much count the units off the grid for the segment CB, so let's just find the lengths of AC and AB,

so, add AC + AB + CB, and that's the perimeter of the triangle.
Answer:
Step-by-step explanation:
hello : here is an solution
A(b)+16 = 16 larger than the product of a and b.
Answer:
its D) x = -8 is correct
All the values less than 7 are included in the number line. The graph on number line is shown in figure attached. In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
