Answer:
14
Step-by-step explanation:
a = 3
b = 4

4 4/5 is the answer. :)
or.. 4.8!
Area of a triangle:
A= (1/2)(bh)
In this problem we are given:
A= 178.5

b= h+4 in
h= UNKNOWN ("h")
Plug in our values into the area equation and solve for "h":


(multiply each side by 2 to get rid of the 1/2)



(357/21=17)

(solve both inequalities separately)


( a negative height is not possible so, this answer is incorrect.)


Answer: base = (h+4)= (17+ 4)
b= 21 in h= 17inPlease comment with any further questions! :)
I pretty sure it is D if you give me a thanks I would really appreciate it
Answer:
9
Step-by-step explanation:
the absolute value function always delivers only the positive value of anything inside the absolute function.
therefore, x is 9 and only 9.
