Answer:
x= -8 , x=5
Step-by-step explanation:
2x^2+6x-80=0
x^2+3x-40=0
look for 2 numbers that their:
sum = 3
product = -40
(x+8)(x-5)=0
thus
x= -8 , x=5 (ANS)
50 is a rational number because it can be expressed in two integers; 50 ÷ 1
Point S makes the two connected angles the same. They both have right angles.
And one side of each is congruent.
This means you know 2 angles are the same and one side is the same.
You would use ASA (Angle, Side, Angle)
30*5=150
32*34=1088
15*19=285
15*3=45
Y=Mx +c
M gradient so count how many squares per one line
C = y intercept (7.5) here it looks
Just sub in those
