Of course girl! Algebra is my thing :)
The correct answer is B, and here's why:
(a+3)^3 is the same as (a+3)(a+3)(a+3)
(a+3)(a+3)=a(a+3)+3(a+3) (distributive property)
a^2+3a+3a+9=a^2+6a+9
And from there we see that all the values match. Hope this helps

B. (a+3)^2= a^2+ 6a+9 (a+3)= a^3+ 6a^2+9a+3a^2+18a+27= a^3+ 9a^2++27a+27 - ---------------------------------

What is x in 3.6x=1.6x+24
Ipatiy [6.2K]

Answer:

x=12

Step-by-step explanation:

3.6x=1.6x+24

We simplify the equation to the form, which is simple to understand

3.6x=1.6x+24

We move all terms containing x to the left and all other terms to the right.

+3.6x-1.6x=+24

We simplify left and right side of the equation.

+2x=+24

We divide both sides of the equation by 2 to get x.

x=12

The radius of a wheel is 21m.how much distance will it covers when it rotates 5 times?​
mrs_skeptik [129]

Answer:

Distance = 660 meters

Step-by-step explanation:

Given the following data;

Radius, r = 21 m

Number of revolutions = 5 times

To find the distance covered;

The distance covered in one revolution is given by the circumference of a circle.

Mathematically, circumfeence of a circle is equal to;

C = 2πr

Substituting into the formula, we have;

C = 2 * 22/7 * 21

C = 44 * 3

C = 132 meters

Next, we find the distance covered;

Distance = Circumference * Number of revolutions

Distance = 132 * 5

Distance = 660 meters
