(x-3) (x-3) +2(x-3) -8=0
(x-3+2)(x-3)-8=0
(x-1)(x-3)-8=0
x^2 -4x +3-8=0
x^2 - 4x -5=0
x^2 -5x +x-5=0
x(x-5)+x-5=0
(x+1)(x-5)=0
x= - 1, 5
Answer:
7
Step-by-step explanation:
rate of change of function not necessary mean linear, it can be the slope of a tangent line.
a: y=8x+3 slope = 8
b: rate of change: 1
8-1=7

Hi there!
So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.
Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.
So the value of x is : 7
And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.
So the value of y° is : 60°
There you go! I really hope this helped, if there's anything just let me know! :)
