Answer:

10x^3+13x^2-15x-67

Step-by-step explanation:

First you distribute- 10x^3+25x^2-40-12x^2-15x-27

                      you distribute the 5 through then the negative 3 through

Then you combine like terms

        10x^3+13x^2-15x-67

Then that is just your answer after you add the ones with the squared together and the ones with no variables together

crimeas [40]

Answer:

The base and height  of the garden are 4.60 ft and 5.60 ft.

Step-by-step explanation:

The area of the garden is, <em>A</em> = 24 ft².

The base height of the garden are:

base (<em>b</em>) = 6x - 4

height (<em>h</em>) = x + 3

Compute the value of <em>x</em> as follows:

A=\frac{1}{2}\times b \times h\\\\24=\frac{1}{2}\times (6x-4) \times (x+3)\\\\48=6x^{2}+18x-4x-12\\\\6x^{2}+14x-60=0\\\\3x^{2}+7x-30=0\\

The last equation is a quadratic equation.

Compute the roots of the quadratic equation as follows:

x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }\\x = \frac{ -14 \pm \sqrt{14^2 - 4(3)(-30)}}{ 2(3) }\\x = \frac{ -14 \pm \sqrt{556}}{ 6 }\\x = \frac{ -14 }{ 6 } \pm \frac{2\sqrt{139}\, }{ 6 }\\x = -\frac{ 7}{  3 } \pm \frac{ \sqrt{139}\, }{  3 }\\x = 1.59661\\x\approx 1.60

The value of base and height are:

\text{base}=6x-4=(6\times 1.60)-4=5.60\ \text{ft}\\\\\text{height}=x+3=1.60+3=4.60\ \text{ft}

Thus, the base and height  of the garden are 4.60 ft and 5.60 ft.

You are hiking on a trail that leads to the top of a mountain. At 1 P.M. you reach an elevation of 4400 feet. At 4 P.M. you reac
shusha [124]
Let
t = time, hours
h = height, feet

At 1 PM, the time and height are respectively
t₁ = 1  hour
h₁ = 4400 feet

At 4 PM, the time and height are respectively
t₂ = 4 hours
h₂ = 5600 feet

By definition, the mean hourly change in elevation is 
\frac{h_{2} - h_{1}}{t_{2} - t_{1}} = \frac{5600-4400}{4-1} = \frac{1200}{3} =400

Answer: 400 feet per hour

Solve for m<br> m/9 + 2/3 = 7/3
V125BC [204]

Answer:

Step-by-step explanation:

Okay so lets put the x values on one side and the whole numbers which are the numbers without variables on the right side.

so now,

m/9 = -2/3 + 7/3

now lets use the inverse operation of division to multiply 9 to separate it from the variable

9(m = -2/3 + 7/3)9

m = -18/3 + 63/3

which can be simplified to,

m = -6 + 21

so,

m = 15.

Hope this helps!
