<h3>
Answer: height = 10 inches</h3>
==========================================================
Explanation:
To get the area of a triangle, we multiply the base (b) by the height (h), then we divide by 2. That leads to the value of A.
So that explains the equation A = b x h/2 which is the same as A = b*h/2
We can multiply both sides by 2 to get 2A = b*h
This flips to b*h = 2A
If we divide both sides by b, then we get the formula
h = 2A/b
The variable h is isolated on its own side.
-----------------------
Next, we'll plug in the given area of A = 60 square inches and the base of b = 12 inches.
This leads to a height of...
h = 2A/b
h = 2*60/12
h = 120/12
h = 10
The height must be 10 inches.
-------------------------
Let's check the answer
So we are given the base of b = 12 and we just found the height to be h = 10.
The area of the triangle is...
Area = (base*height)/2
A = (b*h)/2
A = (12*10)/2
A = 120/2
A = 60
Since we get the proper area, this confirms we have the correct height.
Kathy=k
John=k+6
''Together their ages equal four times Kathys age.''
→k+6+k=4k ; 2k+6=4k ; 2k=6 ;k=3
Kathy=3
John=3+6=9
Answer:
the answer is 4(x)=16
plz mark em as brainliest :)
The answer should be y = 5x^2+4x-1
(2x^3+x+3)/(x+1)=2x^2-2x+3
