Answer:
Step-by-step explanation:
Given that: x
2
+6x+8
=x
2
+4x+2x+8, (split middle term)
=(x
2
+4x)+(2x+8), (group pair of terms)
=x(x+4)+2(x+4), (factor each binomials)
=(x+4)(x+2), (factor out common factor (x+4)
Hence factors of x
2
+6x+8 are (x+4)(x+2)
Answer:
y=2x-3
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
y=2x-3
A= πr2
d=10m
2r=d
2r=10
r=5
A= π•5^2
A=3.14 •25
A=78.5 m^2
