Answer:
The value of x = 23
Step-by-step explanation:
Points to remember
The ratio of of corresponding sides of similar triangles are equal.
<u>To find the value of x</u>
From the figure we can see two similar triangles.
Therefore we can write,
(x - 10)/39 = 5/15
x - 10 = (5 * 39)/15
x - 10 = 13
x = 13 + 10 = 23
Therefore the value of x = 23
Answer:
Speed = 80 m/s
Step-by-step explanation:
The formula to find the speed of a wave is found by
Speed = Wavelength x Frequency where the frequency is in HZ and the wavelength is in meters
Speed = 200 * .40
Speed = 80 m/s
The second 4 is greater than the first one
We have the following equation:
ax2 + bx + c = 0
Using the resolver we have:
x = (- b +/- root (b2 - 4ac)) / 2a
We have:
b2 - 4ac <0
Therefore the root is negative
Answer:
It has two complex solutions
option B
Answer:
yes, it is 26 square units.
Step-by-step explanation:
That shape is just splitted into other shapes, the two small squares fit in that big square.
Hence total area is ( 9+17 ) sq units = 26 sq units
