Answer:
x= -4
Step-by-step explanation:
2x+4=6x+20
so 2x-6x=20-4
divide both sides by -4
-4x/-4 = 16/4
=-4
The formula for the hypotenuse of a triangle is:
[a squared] plus [b squared] = c squared
a and b represent the two sides of the triangle.
You would have to square 8 and 4, add them, then take the square root of it to find the length of the hypotenuse.
<h2>The first equation is correct.</h2>
Answer:
(f+g)(x) = -3x+5
Step-by-step explanation:
f(x)=x+8 and g(x)=-4x-3
(f+g)(x) = f(x) + g(x)
= x+8+-4x-3
= -3x+5
Use the FOIL method (first, outside, inside, last) to multiply:
2x^2-8x+3x-12
This can be simplified even more into:
2x^2-5x-12.
