Answer:
add five to 3.7
Step-by-step explanation:
aka 3.7+5=x
8.7=x
i think
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
-71
1756
Mark brainliest please
Hope this helps you
To work this out, we must use the balancing method - whatever we do to one side, we do exactly the same to the other
-7 = e/3 + 14
(-14) (-14)
-7 - 14 = -21
-21 = e/3
(x3) (x3)
-21 x 3 = -63
-63 = e
e = -63
I'll help you later ok sorry tho
