The rectangle below has an area of 70y^8+30y^6.The width of the rectangle is equal to the greatest common monomial factor of 70y

swat32

Answer:

Width $10y^6$ units

Length $7y^2+3$ units

Step-by-step explanation:

The rectangle has an area of $70y^8+30y^6.$

The width of the rectangle is equal to the greatest common monomial factor of $70y^8$ and $30y^6.$ Find this monomial factor:

$70y^8=2\cdot 5\cdot 7\cdot y^8\\ \\30y^6=2\cdot 3\cdot 5\cdot y^6\\ \\GCF(70y^8,30y^6)=2\cdot 5\cdot y^6=10y^6$

Hence, the width of the rectangle is $10y^6$ units.

The area of the rectangle can be rewritten as

$10y^6(7y^2+3).$

The area of the rectangle is the product of its width by its length, then the length of the rectangle is $7y^2+3$ units.

What is the volume of a sphere with a diameter of 8 m use 3.14 for pie round your answer to the nearest hundredth

deff fn [24]

Volume of the sphere is 300 m³

Step-by-step explanation:

Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m

⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)

Answer:

$\frac{11x}{3y}$

Step-by-step explanation:

$\frac{7x}{3y} + \frac{12x}{9y}$

Make both a single fraction by adding together.

$\frac{3(7x) + 1(12x)}{9y}$

$\frac{21x + 12x}{9y}$

$\frac{33x}{9y}$

Simplify

$\frac{3(11)x}{3(3y)}$

$\frac{11x}{3y}$
