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)
All you have to do is multiply both numbers and you get 1.875
Answer:
I believe the answer is D; 5/20+(-12/20).
Step-by-step explanation:
1/4-3/5
5/20-12/20
-7/20
5/20+(-12/20)
5/20-12/20
-7/20
Hope this helps! :D
Area of a square= length^2
479=length^2
√479= length
so length= 21.89ft rounded to 22ft
