9x6 = (__)?
16y6 = ()2
Then use a? - b2 = (a - b)(a + b). Show your work.
9x6 – 16y6 =
Answer:
(3x^3 - 4y^3) ( 3x^3 + 4y^3)
Step-by-step explanation:
9x^6 – 16 y^6
Rewriting as
(3x^3) ^2 - ( 4y^3) ^2
This is the difference of squares a^2 - b^2 = (a-b)(a+b)
(3x^3 - 4y^3) ( 3x^3 + 4y^3)
Answer:
(3x^3 - 4y^3) ( 3x^3 + 4y^3)
−7

Answer:
x = 7
Step-by-step explanation:
Add 3x to both sides of the equation.
2x = 6+8
Divide both sides by 2.
x = 7
Answer:
7
Step-by-step explanation:
Answer:
Amount needed by Zoya to meet her fundraising goal ≥ $ 300
Number of Bracelets possessed by Zoya = 100
Cost of single bracelet = $ 5
To meet her goal , we need to convert these statement into equation
Let number of Bracelets sold = x
1. x≤ 100
2. 5 x ≥ 300
Dividing both sides by 5, we get
x ≥ 60
The two inequality are : x ≤ 100 and x ≥ 60
So the inequality is : 60 ≤ x≤ 100.

Answer:
The area of the doghouse is
Step-by-step explanation:
we know that
The area of trapezoid is equal to
where
b1,b2 are the parallel bases of trapezoid
h is the height of trapezoid
in this problem we have
substitute
Answer:
32.5 square feet
Step-by-step explanation:
The area of the triangle is 7.5 and the area of the rectangle is 25 so then add 25+7.5 and the answer si 32.5
Step-by-step explanation:
A) width × length = area
300 ft × l = 48000 sq ft
B) l = 48000 ÷ 300
l = 160 ft
Answer: The radius of a sphere is 5.20 cm.
Step-by-step explanation:
Volume of sphere = , where r = radius of sphere.
Given : Volume of sphere : 589 cubic centimeters
