Hello :
the midepoint is( (-1+7)/2 ; (3+2)/2)
(3, 5/2) ... answer C
I think it is...... -6x-5
Answer:
121 inches squared
Step-by-step explanation:
If the dimensions are multiplied by 1/4, we have that the surface area will by multiplied by (1/4)^2, as the dimensions are in inches and the surface area is in inches squared.
So, If the original surface area is 1936 inches squared, the new surface area will be:
New surface area = 1936 * (1/4)^2 = 1936 / 16 = 121 inches squared.
Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25
then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm
