Step-by-step explanation:
(1+3x-1)×{1-(3x-1)}
=3x.(1-3x+1)
=3x.3x
=9x^2.
Answer:
36 inches
Step-by-step explanation:
lets think of it as a ratio,
80:w
20:9
so we want 20 to get to 80
and 9 to get to w right?
so if we just move the smaller rectangle to the corner, then 20*4=80 right?
and if we do that, we do it to 9 as well, 9*4=36
w=36
Answer:
105
Explanation:
Adding 5% of 100, to 100 is:
100(0.05) + 100
The extra 100 is added because 100(0.05) only gives you what 5% of 100 is.
Answer:
y=-1/3x + 33
Step-by-step explanation:
You can start by writing this in point slope form and converting to slope intercept later. Since the slope of the perpendicular line is y=3x-30, this line must have a slope of -1/3. It's point slope form is therefore:
y-25=-1/3(x-24)
Now, you can convert to slope intercept by isolating y:
y=-1/3(x-24)+25
y=-1/3x+8+25
y=-1/3x+33
Hope this helps!
