Multiply and simplify. 2x4yx⋅6xy2z3

OLEGan [10]

Answer:

The given expression $2x^4yx \times 6xy^2z^3$ on multiplying is $12x^6y^3z^3$

Step-by-step explanation:

Consider the given two expressions $2x^4yx$ and $6xy^2z^3$

We have multiply both expressions,

$2x^4yx \times 6xy^2z^3$

To multiply two terms first multiply constant numbers that is 6 × 2 = 12

For x , y and z apply property of exponent,

$x^a\cdot x^b=x^{a+b}$

Then power of x together will be,

$x^4\cdot x\cdot x=x^{4+1+1}=x^6$

Similarly for y powers,

$y \cdot y^2=y^{1+2}=y^3$

Since first term do not have any expression for z so it will remain same.

Thus, the given expression on multiplying become,

$2x^4yx \times 6xy^2z^3$ is $12x^6y^3z^3$

Elainas old bicycle had tires with a 12-inch diameter her new bicycle had tires with a 16-inch diameter what is the difference i

mr Goodwill [35]

Answer:

The difference between the circumference of the tires is 12.56 inches.

Step-by-step explanation:

Given:

Diameter of old bicycle tires = 12 inch

Diameter of new bicycle tires = 16 inch

We need to find the difference in circumference of the tires.

Solution:

First we will find the circumference of Old bicycle tires.

Circumference can be calculated by π times diameter.

Circumference of Old bicycle tire = $\pi \times 12 = 37.68\ in$

Now we will find the circumference of new bicycle tire.

Circumference of New bicycle tire = $\pi \times 16 = 50.24\ in$

Now to find the difference between the circumference of the tires we will subtract Circumference of New bicycle tire from Circumference of Old bicycle tire we get;

framing in equation form we get;

difference between the circumference of the tires = $50.24-37.68 =12.56\ in$

Hence The difference between the circumference of the tires is 12.56 inches.

an isosceles triangle has a vertex angle of 21.21 degrees. two sides of the triangle are each 17.91 ft long. whats the area of t

lubasha [3.4K]

Answer:

The area of triangle is $A=58.02\ ft^{2}$

Step-by-step explanation:

Let

B -----> the measure of the vertex angle of the isosceles triangle ABC

a and c -----> the two congruent sides of the isosceles triangle ABC

we know that

The area of a triangle applying the law of sines is equal to

$A=\frac{1}{2}(a)(c)sin(B)$

we have

$a=c=17.91\ ft$

$B=21.21\°$

substitute in the formula

$A=\frac{1}{2}(17.91)(17.91)sin(21.21\°)$

$A=58.02\ ft^{2}$
