Answer:
Side is 8 meters, Perimeter is 32 meters
Step-by-step explanation:
<em>One side </em>
Squares have 4 equal sides. Area is found using l*w, but the sides are all equal in squares. Therefore, the area can be found using:
a=s^2
We know the area is 64, so we can substitute that in
64=s^2
Take the square root of both sides

8=s
One side is 8 meters
<em>Perimeter</em>
Squares have 4 equal sides, and the perimeter is all the sides added up.
p=s+s+s+s
We know the side is 8, so we can substitute that in
p=8+8+8+8
p=4*8
p= 32
The perimeter is 32 meters
It would take 5 yrs. for both trees to be the same height.
Answer:
i think 27
Step-by-step explanation:
27 X 4/3y=36y
Answer:
y = 5x/2 + 2
Step-by-step explanation:
We know the equation for slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Since we have the coordinates of one point on this line and the slope, we can substitute that in and find b first:
y = mx + b
-8 = 5/2(-4) + b
-8 = -10 + b
b = 2
So we can use the slope and this y intercept we found to plug back into the equation:
y = mx + b
y = 5x/2 + 2
