Perimeter is the distance around an object / shape. Area is the amount of space within a 2 dimensional surface. For example the perimeter of a square would be the lengths of each side added together while the area would be how much space inside of it that it occupies. Area is measured in units squared, while perimeter is left in just units. In other words if the unit ( measurements ) are conducted in cm, then the area would be put in cm^2. The perimeter would just remain in cm.

7. the wall is 12 the ladder is 15 find the ground
this will make a right angle from the wall and the ground
a^2+b^2=c^2
12^2+b^2=15^2
144+b^2=225
-144 both sides
b^2=81
square root both sides
b=9 ft
8. area of square is s^2
s^2=81
square root both sides s=9cm
diagonal=
a^2+b^2=c^2
9^2+9^2=c^2
81+81=c^2
162=c^2
square root both sides
12.73cm is diagonal
9. a^2+b^2=c^2
a=9
b=12
c=
9^2+12^2=c^2
81+144=c^2
225=c^2
square root both sides
c=15km
Answer:
y=x÷2
Step-by-step explanation:
substitute g(x) with y
y= 2(x-3)2+4
switch x and y in the equation
x=2(y-3)2+4
solve for y:
x=2(y-3)+6
x-6=2(y-3)
(x-6)/2=y-3
(x/2)-3=y-3
x÷2= y
Answer:
h = 8 units
Step-by-step explanation:
We see similar triangles
AD = 20 - 4 = 16 units
since AC = AD + DC = 16 + 4 = 20
so
16: h = h: 4 where corresponding sides are in proportion.
so ... cross multiply in this proportion and solve for h
64 = h^2
h = 8 units it looks like choice F.)
