Answer:
x^2+7x+10
Step-by-step explanation:
area = Pi*r^2
= Pi*10^2
=100Pi
=314.1592654
circumference = Pi*Diameter
= Pi*20
=20Pi
=62.83185307
Answer:
Step-by-step explanation:
-2x + 3y = 6.....(x, -4)...so y = -4
-2x + 3(-4) = 6
-2x - 12 = 6
-2x = 6 + 12
-2x = 18
x = -18/2
x = -9
so the value of x is -9.....(-9,-4)
The first one.... y=$21x-$180
Hope this helps!!
