expand the expression (5x-y)^3 using the binomial theorem
please help thank you
Answer:
n = 18
Step-by-step explanation:
(2n) and (n + 18) are vertically opposite angles and are congruent, then
2n = n + 18 ( subtract n from both sides )
n = 18

how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³
so
15. Circle all of the expressions equivalent to 9x - y.
A (3x2 - y)
B. (3x)2-0)
C 9(x2)-6)
D. (932) 2-6)
E. (3x2 + y)(3x2-y)
Answer:
I believe a is One of them
The first equation is y = -2x + 8
and the second is
y = x - 4
Please show your work!!!
Answer:4
Step-by-step explanation:
y=-2x+8
y=x-4
Y equals the same thing so you can do equal values method
-2x+8=x-4
+2x +2x
__________
8=3x-4
+4 +4

Answer:
Step-by-step explanation:
tan Ф = opposite side divided by the adjacent side
tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator

The volume of this cylinder is 175pi cubic units. What is the volume of a cone that has the same base area and the same height? Write your answer in terms of pi.
Answer: 58.33π units ³
Step-by-step explanation:
The volume of a cylinder = πr²h
The volume of a cone = 1/3πr²h
Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:
= 175π / 3
= 175/3π
= 58.33π units ³
The volume of the cone is 58.33π units ³
Answer:
183
Step-by-step explanation:
When multiplied by pi, it rounds out to 183.

What is the área of this figure? (I need the answer bc this Is due in 1 hr )
Answer: 353ft
Step-by-step explanation:
To work out what the area of this composite shape is, you would split it into two shapes; a square and a rectangle.
For the formula of the rectangle and square you would do base x height.
So,
For the square you do 13x13=169
For the rectangle you would do 23x8=184
Then to work out the total area of the two shapes you would add the two areas together.
169+184=353

Diego is asked to solve 3x−8=4(x+5). What do you recommend he does to each side first?
Answer:
He would factor out 4(x+5)
Step-by-step explanation:
You can't do much until the 4(x+5) is factored out.
Once it is then it'd be 3x-8=4x+20
Then you subtract 3x on both sides and subtract 20 on both sides.
You'd be left with -28=x
Hope this helps
