Answer:

8x^3+60x^2+150x+125

Step-by-step explanation:

(2x+5)^3=(2x+5)(2x+5)^2 =

(2x+5)(4x^2 +2*2x*5+25)=

(2x+5)(4x^2 +20x+25)=

(2x*4x^2 +2x*20x+2x*25+5*4x^2+5*20x+5*25)=

8x^3+40x^2+50x+20x^2 +100x+125=

8x^3+60x^2+150x+125

A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centim
Daniel [21]
The answer is 1808.64 ft²

To calculate area of square we need to find radius r. Radius is a half of a diameter:
r = d/2

The blueprint:
d = 18 cm
r = 18/2 = 9 cm

<span>The blueprint has a scale of three centimeters to four feet. Actual radius r1 is:
</span>3 cm : 4 ft = 18 cm : r1
After crossing the products:
r1 = 4 ft * 18 cm : 3 cm
r1 = 24 ft

The area of the circular base of the fountain is:
A = r1² * π
π = 3.14
r1 = 24 ft

A = 24² * 3.14
A = 1808.64 ft²

Y = -2x + 8<br> y = x^2 - 9x + 18<br><br> solve the system of nonlinear equation
ryzh [129]

Substitution

-2x+8=x^2-9x+18

x^2-7x+10=0

Factoring, we get

(x-5)(x-2)=0

x=5, x=2

If x equals 5,

y=-2(5)+8=

-10+8=

-2

Therefore, we derive our first solution:

<h2><u><em>x=5,</em></u></h2><h2><u><em>y=-2</em></u></h2>

Now we solve for our second x

If x=2,

y=-4+8=

4

Therefore, we derive our second solution:

<h2><u><em>x=2</em></u></h2><h2><u><em>y=4</em></u></h2>

<u><em></em></u>
