Step-by-step explanation:

Answer:
28
Step-by-step explanation:
this is a function
if h(x) is -8 you would plug it in for x:
-4(-8) -4 a negative × a negative is a positive
32- 4= 28
Answer: 
Explanation:
The equation is:

The term on the left consists of a product of two different factors: therefore, this product can be zero if either the first term (2x-5) or the second term (3x-1) is equal to zero.
This means that we can solve separately for the two terms:

Solving the first equation:

Solving the second equation:

The closest distance up the tree where the wire reaches is 17.93 foot.
<u>Explanation:</u>
Given-
Length of the wire, L = 12 foot
angle, Ф= 48°
Distance upto which the wire reaches the tree, x = ?
We know,
cos Ф = base/ hypotenuse
cos 48° = 12/ x
0.669 = 12/x
x = 17.93 foot
Therefore, the closest distance up the tree where the wire reaches is 17.93 foot.
