Answer:

4x² + 12x + 9

Step-by-step explanation:

<h3>Using identity: </h3>

(a +b)² = a² + 2ab + b²

Here, a = 2x  & b = 3

(2x +3 )² = (2x)² +  2*2x*3 + 3²

              = (2x*2x)  + 12x + 3*3

             = 4x² + 12x + 9

Answer:

16.86 ft/s

Step-by-step explanation:

Given that

Speed of the carousel, s = 14 rpm

Distance from the carousel, d = 23 ft

To start with, we convert the given speed to revolution per second, so that

s = 14/60 rev/sec

To find the needed speed, we use the formula

v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD

v = πnD, and we use this to find our needed velocity

v = 3.142 * 14/60 * 23

v = 72.266 * 14/60

v = 16.86 ft/s

Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it

Solve the following equation for x, in terms of a and b. ax = 15 + bx
charle [14.2K]

Value of x will be x=\frac{15}{a-b}.

Equation given in the question → ax=15+bx

To find the value of 'x' in terms of a and b, we will simplify the given equation,

ax=15+bx

ax-bx=(15+bx)-bx

x(a-b)=15

x=\frac{15}{a-b}

           Therefore, Values to filled → Blank 1 = 15

                                                           Blank 2 = (a - b)
