The freezing point of water.
Common difference = 2nd term - first term
= -13-(-6)
= -13+6
= -7
Answer:
Step-by-step explanation:
This is hard
Y=mx+b
M is the slope
B is the y intercept
In this case 4 is the slope and -9 is the y intercept
Yo sup??
Lenght of two side will be equal to 20 in as its an isoceles triangle.
The third side will be
x^2=b^2+h^2 (by pythagoreas theorem)
=9^2+9^2
x=9√2 in
Therefore the perimeter is = 9+9+9√2
=9√2(√2+1) in
Hope this helps.
