Answer:
a square has 4 sides each of those sides is 19in long perimeter is all around the square so you would add 19+19+19+19=79in
There are 2 x’s so it’s 2x^2 + 9x because 2x4 is 8 + 1 x and then + 4 because you connect like terms so it would be 2x^2+9x+4
Answer:
Right angle
Step-by-step explanation: you take the 57% angle and ad that with
the 33% angle and you got a prefect 90% also known as a "Right angle"
Slope = (0 - 4)/(-5-5) = -4/-10 = 2/5
y = mx + b
4 = (2/5) (5) + b
4 = 2 +b
b = 2
equation
y = 2/5x + 2
