I CAN HELP YOUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!1
lets distribute 7(x+3)
so 7(x)+7(3)
7x+21 or b
yay :)

Here's the explanation ~
Zeros or roots of a function is the value of independent variable (usually x - coordinate or absicca) where the value of dependent variable (y - coordinate or ordinate) is 0.
That is :
The point where it cuts the x - axis, it has an x - coordinate = -6
Therefore, we can conclude that The zero of given function is -6
Answer:
4
Step-by-step explanation:
the scaling factor is 1.5 to go from DEF to QRS.
so,
EF × 1.5 = RS = 6
EF = 6 / 1.5 = 6/1 / 3/2 = 6×2 / 1×3 = 12/3 = 4
Answer:
53.7 miles per hour
divide the speed value by 17.6
