Answer:(0.6,10.6) after 8 seconds.
Step-by-step explanation:
Let length be l
and breadth be b
perimeter = 28
2(l+b) = 28
l + b = 14
l = 14 - b
area = 48
l x b = 48
(14 - b) b = 48
14b - b^2 = 48
b^2 - 14b + 48 = 0
b^2 -6b - 8b + 48 = 0
b( b - 6 ) - 8 ( b - 6) = 0
(b-8) ( b-6) = 0
so
either b = 8 or b = 6
if b= 8
l = 14 - 8 = 6
( not possible as length cannot be smaller than breadth)
so
breadth = 6
length = 8
So the formula for this type of question is a(square) + b(square)=c(square)
so it would be x+30x30 = 50x50
x+900= 2500
x= 2500-900
x= 1600
since it’s you want to find the length without the root , do square root of 1600 , which is 40
So it’s B
Answer:
y=1/5x+5
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y- needs to be by itself in this form.
m- the slope.
x- always to the right side of the slope, or m.
b- y-intercept.
Now that we know this, all we have to do is plug in the numbers we have. So when we plug this in, the equation looks like this:
y=1/5x+5
Hope this helps you and have a great day :3
