Yes this is correct. if you do distribution and multiply 2 times x it's 2x. you then multiply 2 times 6 and this equals 12. add twelve and 8 and this equals 20. the answer 2x+20 is correct
the answer is x=-4 hope it helps
We have the following equation:
V = kr ^ (2) h
For cylinder A we have:
251.2 = k * ((4) ^ (2)) * (5)
Let's clear k:
k = 251.2 / (((4) ^ (2)) * (5))
k = 3.14
For cylinder B we have:
V = 3.14 * ((3) ^ (2)) * (9)
V = 254.34 in ^ 3
Answer:
the volume of cylinder B is:
V = 254.34 in ^ 3
Answer:
(-6,-4) is the new coordinate for the image after it is reflected over the x-axis.
Step-by-step explanation:
Answer:
length = 62.41 inches
Step-by-step explanation:
Using pythagoras theorem -
Let
a = hypotenuse
b = height
c = length
a^2 = b^2 +c^2
75^2 = 41.6^2 + c^2
Therefore,
75^2 - 41.6^2 = c^2
5625 - 1730.56 = c^2
389.44 = c^2
square root (389.44) = c
62.40544848 = c
