<h3>
Answer: 2x^2 + 6x - 4</h3>
=================================
Work Shown:
f(x) - g(x) = [ f(x) ] - [ g(x) ]
f(x) - g(x) = ( 3x^2+x-3) - ( x^2-5x+1 )
f(x) - g(x) = 3x^2+x-3 - x^2+5x-1
f(x) - g(x) = (3x^2-x^2) + (x+5x) + (-3-1)
f(x) - g(x) = 2x^2 + 6x - 4
Answer:
8 units squared
Step-by-step explanation:
Here's the formula of a triangle
base*height divided by 2
So, we know that the base is 4.
We have to work backwards.
16*2 is 32
32 divided by 4 is 8.
Now let's see
8*4 is 32 divided by 2 is 16!
Hope you understand :)
For 70 people i would say ab 445
Answer:
x=-2.5,9
Step-by-step explanation:
Set them equal to each other to say 2x^2-9x=4x+45. Get them all on one side to get 2x^2-13x-45. Factor that out to get (x+2.5)(x-9). Set that equal to 0 to get x=-2.5,9
If you are trying to find h, then its very simple.
So lets see 5+7=12
So 17-12=5
So lets check to see if h=5
5+5+7
5+5=10+7=17 so h is 5. :)
