Given:
The radical expression is
[tex]7\sqrt[3]{8x^2y}+2\sqrt[3]{27x^5y^4}[/tex]
To find:
The value of the expression after addition.
Solution:
We have,
[tex]7\sqrt[3]{8x^2y}+2\sqrt[3]{27x^5y^4}[/tex]
It can be rewritten as
[tex]=7\sqrt[3]{2^3x^2y}+2\sqrt[3]{3^3x^3x^2y^3y}[/tex]
[tex]=7(2)\sqrt[3]{x^2y}+2\sqrt[3]{(3xy)^3x^2y}[/tex]
[tex]=14\sqrt[3]{x^2y}+2(3xy)\sqrt[3]{x^2y}[/tex]
[tex]=14\sqrt[3]{x^2y}+6xy\sqrt[3]{x^2y}[/tex]
Taking out the common factors, we get
[tex]=2\sqrt[3]{x^2y}(7+3xy)[/tex]
The value of given expression after addition is [tex]=2\sqrt[3]{x^2y}(7+3xy)[/tex].

Answers
Answer:
10a - 30b + 40
Step-by-step explanation:
Multiply each term inside the ( ) by the 5 outside the ( ).
5 x 2a = 10a
5 x -6b = -30b
5 x 8 = 40
Add the terms together (don't forget that it's negative 30b)
10a + -30b + 40 = 10a - 30b + 40
5 and2/3 divide by 4?
Answers
Answer:
The answer is 1 5/12 or 17/12.
Step-by-step explanation:
First we turn 5 2/3 into a Improper fraction.
5 2/3 = 17/3
Next we change 4 to 1/4 then multiply 1/4 by 17/3.
17/3 * 1/4 = 17/12
17/12 = 1 5/12
Hope this helps! :)
Answer:
17/12
Step-by-step explanation:
5[tex]\frac{2}{3}[/tex] / 4 = [tex]\frac{17}{3}[/tex] / [tex]\frac{4}{1}[/tex] = [tex]\frac{17}{3}[/tex] * [tex]\frac{1}{4}[/tex] = 17/12

Actually Welcome to the Concept of the exponents and indices.
here, we should remember one thing that,
3 ^3 = 27 and 1/3^x = 3^-x
so we get as,
(3^-3)^4-x = (3^3)^2x-1
==> 3^-12+3x = 3^6x-3
since the base is same that is 3 , we equate their powers.
-12x+3=6x-3
==> 3+3 = 6x+12x
==> 6 = 18x
hence ===> x = 6/18 = 1/3
hence, x = 1/3

-4x + 16 = y
2x - 32 = 2y
Step 2: Solve for x
Substitution
Substitute in y: 2x - 32 = 2(-4x + 16)Distribute 2: 2x - 32 = -8x + 32[Addition Property of Equality] Add 8x on both sides: 10x - 32 = 32[Addition Property of Equality] Add 32 on both sides: 10x = 64[Division Property of Equality] Divide 10 on both sides: x = 32/5Step 3: Solve for y
Define original equation: -4x + 16 = ySubstitute in x: -4(32/5) + 16 = yMultiply: -128/5 + 16 = yAdd: -48/5 = yRewrite/Rearrange: y = -48/5The perimeter of a triangle is 26 feet. The second side is twice as long as the first. the third side is 1 foot longer than the second side. What is the length of the 3 sides?
Answers
Answer:
5, 10 and 11 feet.
Step-by-step explanation:
Let length of first side be x feet then
second side = 2x feet
third side = 2x + 1 feet.
So we have the equation:
x + 2x + 2x + 1 = 26
5x + 1 = 26
5x = 25
x = 5 feet.
So first side = = 5 feet, second = 10 and third = 11 feet.
Plentiful Pies determines its annual profits
in dollars using p(x) = 65x - 0.3x2 where x
represents the numbers of pies sold. If Plentiful
Pies sells 175 pies in a year, what will their
annual profits be?
Answers
Answer:
The annual profits will be 2187.5
Step-by-step explanation:
p(x) = 65x - 0.3x^2
I am guessing that the 2 was supposed to be a square.
Simply plug in the number of pies sold:
p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5
What is the equation of the line that passes through the point (-5, 7) and
has a slope of - 1/5?
Answers
Answer:
[tex]y=-\frac{1}{5}x+6[/tex]
Step-by-step explanation:
We have the following equation
y=mx+b
where m is the slope
and b is the y intercept
we know that the slope is -1/5 (or -.2)
which means that so far our equation looks like this
y= -.2x+b
which means we need to solve for b
we know that when x= -5 y= 7 which means we can plug in those values and solve for b
we have
7= (-.2*-5)+b
7=1+b
b=6
which means our equation is as follows
y= -1/5x+6
