Answer:
The answer is 6
Step-by-step explanation:
A=½(b1 + b2) h
we substitute
Area=75
the two bases are 10 and 15
75=½(10+15) h
75=½(25)h
75=(1*25/2)h
75= 25h/2
75/1= 25h/2
25h*1= 75*2
25h= 150
we divide by 25
25h/25= 150/25
h=6
Given:
The equation is

To find:
The value of x.
Solution:
We have,

Isolating the variable, we get




Therefore, the value of x is 44.2.
Answer: 3. (3,-3) and 4. (-3,4)
Step-by-step explanation: Number 4 is self explanatory of what they are and number 3, you need to figure out what minus 6 equals -3 and that happens to be 3.
To find the height of the TV you first need to realize that the question is giving you dimensions for a triangle.
Every triangle has a hypotenuse and two sides. To find the hypotenuse you square both sides, add them, and then square root. So to find one of the sides you get the hypotenuse, square it, and subtract the square length of the given side.
The equation is 25^2-20^2.
Which if simplified is 625-400, the then solution is going to be 225.
You next will square root 225, 225^(1/2). Which your answer should be 15 inches for the missing side length.
