Answer:
B. H1= b1=0
Step-by-step explanation:
the alternative hypothesis is correct
(6x-18)(x+4)/(3x-9)=6(x-3)(x+4)/3(x-3)=2(x+4)=2x+8
Answer:
12 inches
Step-by-step explanation:
So you know that the perimeter of a picture frame (a rectangle) is 2 widths plus 2 lengths.
Let x= lengths and w= widths
From the question we already know that w=7, so we can set up an equation that says:
2x + 2w = 38
2x + 2(7) = 38
2x+14 = 38
2x +14 -14 = 38-14
2x = 24
2x/2 = 24/2
x= 12
Since x= lengths =12
the length of the frame is 12 inches.
Answer: -2,000,000
Step-by-step explanation:
Think of it as -3,000,000 + 1,000,000
Answer:
8x+2y+3x-18y+x^2
final answer: x^2+11x-16y
