$\sqrt[3]{16x^7}\cdot\sqrt[3]{12x^9}=\sqrt[3]{16\cdot12\cdot x^{16}}=\sqrt[3]{4\cdot4\cdot4\cdot3\cdot x^{15}\cdot x}=\\\\=\sqrt[3]{4^3}\cdot\sqrt[3]{x^{15}}\cdot\sqrt[3]{3x}=\boxed{4x^5\sqrt[3]{3x}}$

$\\ \sf\longmapsto 2(L+B)=55$

$\\ \sf\longmapsto 2(\dfrac{4}{3}x+x)=55$

$\\ \sf\longmapsto \dfrac{8}{3}x+2x=55$

$\\ \sf\longmapsto \dfrac{8x+6x}{3}=55$

$\\ \sf\longmapsto \dfrac{14x}{3}=55$

$\\ \sf\longmapsto 14x=165$

$\\ \sf\longmapsto x=11.78$

$\\ \sf\longmapsto x\approx 12$

Now

B=x=12
L=4/3(12)=4(4)=16

X=2y-4 7x+5y=-66 what is the x- value

Gwar [14]

Answer:

x = -8

Step-by-step explanation:

x = 2y - 4 --- Equation 1

7x + 5y = -66 --- Equation 2

I will be using the substitution method to solve this.

Substitute x = 2y - 4 into Equation 2:

7x + 5y = -66

7(2y - 4) + 5y = -66

Evaluate.

14y - 28 + 5y = -66

Evaluate like terms.

19y - 28 = -66

Isolate 19y.

19y = -66 + 28

= -38

Find y.

y = -38 ÷ 19

y = -2 --- Equation 3

Substitute y = -2 into Equation 1:

x = 2y - 4

x = 2(-2) - 4

Evaluate.

x = -4 - 4

x = -8

Factor completely 20x3y + 30x2y2.

Alexxandr [17]

10x2y(2x + 3y)

Each term has 10 in it. Plus each term has at least 2 x's and 1y. The parenthesis are what's left over.
