4(5x+1)(5x-1) = 0
1. Take out the GCF (in this case, 4)
4(25x^2-1) = 0
2. This can be further factored. Factor the values within the parenthesis
4(5x + 1)(5x -1) = 0
Answer:
a*(1 -0.5)*(1 +0.5) = 0.75a . . . . the original number "a" is larger
(a/(0.75a) -1) * 100% = 33 1/3% . . . . the original number is larger by 33 1/3% of the revised number
Step-by-step explanation:
1 3/4 is greater than 0.75 because 1 3/4 is 1.75 and it is greater than 0.75
Answer:
75
Step-by-step explanation:
Area of a triangle is <em>l </em>x <em>w </em>(length x width)
That's 4 cm x 12 cm. Now you could go ahead and figure it out from there, but you have to remember it wants the answer in meters. It tells us that for every 4cm, it is 5m. The easiest way to figure this out is to convert to meters before multiplying. Since 4 cm is 5m, the <em>l </em>becomes 5m. 4 goes into 12 three times. So we would do 5 x 3 to get 15m for the new <em>w. </em>Now we can solve for area.
<em>l </em>x <em>w </em>= A
5m x 15m = A
75m = A
I hope this helped :)
Answer:
Step-by-step explanation:
Begin by transferring 1/10 x to the right hand side.
y = - 1/10 x + 3
Since the equations are identical, they have infinitely many solutions.
