Answer:
x = 10.0
Step-by-step explanation:
Using the geometric mean formula:
x projection
----------------- = ---------------
entire base x
Here, the projection is 5 and the entire base is (20 + 5). So:
x 5
------------ = ------------
25 x
Cross multiply:
x² = 25 (5)
x² = 100
√x² = √100
x = 10
Answer:
a
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
let x be the other leg to be found, then
155² = 124² + x²
24025 = 15376 + x² ( subtract 15376 from both sides )
8649 = x² ( take the square root of both sides )
= x
Hence x = 93 cm ← length of other leg → a
Answer:
Henny = (x-8) dollars
Step-by-step explanation:
Janet's has x dollars.
Henny has $8 less than Janet. It means, the difference between the dollars own by Janet's and Henny is 8.
Henny has = (x-8) dollars
Hence, the expression that shows dollars Hanley has is (x-8).
<span>2X +1=-15
Subtract 1 from both sides
2x=-16
Divide 2 on both sides
Final Answer: x=-8</span>
