This is the concept of algebra, to get the difference of the expression given we proceed as follows;
(k^2-9k+20)-(k^2-9k+20)
collecting like terms we get:
(k^2-5k^2)+(-9k-9k)+(20-20)
=-4k^2-18k+0
=-4k^2-18k
The answer is (-4k^2-18k)
Answer:
y- intercept is 'b'
Step-by-step explanation:
<u>Explanation</u>:-
Equation of the line having a slope 'm' and y- intercept 'c' is y=mx+c
slope - intercept form is y = mx +c
In given equation y = mx +b comparing y = mx +c
In above equation 'm' is the slope of the line = tan θ , θ be the angle
and y- intercept is 'b'
Answer:
No Possible Triangles
Step-by-step explanation:
Pythagorean theorem. A^2+B^2=C^2.
So 12^2+16^2=c^2
144+256=c^2
400=c^2
square root of 400=c
So C=20
