Step-by-step explanation:

(x-2)(2x+3)(x+1)

=x(2x+3)-2(2x+3)(x+1)

=(2x^2+3x-4x-6)(x-1)

=(2x^2-x-6)(x-1)

=2x^2(x-1)-x(x-1)-6(x-1)

=2x^3-2x^2-x^2+x-6x+6

=2x^3-3x^2-5x+6

( x - 2 )( x + 1 )( 2x + 3 ) =

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

2x^3 - 2x^2 - 4x + 3x^2 - 3x - 6 =

2x^3 + ( -2 + 3 )x^2 + ( - 4 - 3 )x - 6 =

2x^3 + x^2 - 7x - 6

write what you know

the flat fee doesnt chamge no matter how much he uses his data

the charge for every gigabyte does change

Ex: if he uses 3 gigabytes of data in one month, that's

5 + 5 + 5 = $5 x 3 = $15

So taking this into consideration youd write the following

$41.50 + $5x = $52.50 (since this is what we want to equal)

then solve for x

Answer:

Step-by-step explanation:

1.  Find the circumference of the cylinder:  C = 2πr

2.  Multiply this result by the height of the cylinder:  A = 2πr·h

3.  To this result add the surface areas (there are two) of the ends of the cylinder:  2πrh + 2πr²

This is the correct general formula for the surface area of a cylinder of  radius r and height h.  If you want specific numbers, please share the values of r and h.

Answer:

[tex]W=15ft[/tex]

[tex]L=20ft[/tex]

Step-by-step explanation:

From the question we are told that:

Length of Bed [tex]L=5+W[/tex]

Width of sidewalk [tex]W_s=3ft[/tex]

Area of the bed and sidewalk [tex]A_t= 546ft^2[/tex]

Generally the equation for Area of the bed and sidewalk[tex]A_t[/tex] is mathematically given by

 [tex]Area=L*B[/tex]

 [tex]A_t=((3+3)+L)*((3+3)+W)[/tex]

Therefore

 [tex]546=((3+3)+(5+W))*((3+3)+W)[/tex]

 [tex]0=((6+(5+W))*((6)+W)-546[/tex]

 [tex](11+W)*(6+W)-546=0[/tex]

 [tex]W^2+17B-480=0[/tex]

Solving the Quadratic Equation

 [tex]W=15ft[/tex] (Using only positive root)

Generally the Length L is mathematically given by

 [tex]L=5+15[/tex]

 [tex]L=20ft[/tex]

Step-by-step explanation:

Start at (-2, 0).  The curve (a sinusoidal) continues to the right and ends at (6, 0).  That's an interval of 8.  Then, after another 8 units on the horizontal axis, the curve repeats itself again.  This is a "periodic function," with period 8.

Answer:

Step-by-step explanation:

[tex]\frac{2}{5}*85[/tex]

Long way

[tex]\frac{85}{1}*\frac{2}{5} \\ \\ \frac{170}{5} \\ \\ =34[/tex]

short way

-can be simplified before mulitplying

[tex]\frac{85}{1} *\frac{2}{5} \\ \\ \frac{17}{1}*\frac{2}{1} =34[/tex]

Think 85 and 5 as nickels. You need 20 nickels to make 100. Subtract 100 by 85 to get 15. You get 3 nickels and 17 nickels. 17 is the common factor. Multiply 17 by 2 to get your answer.

Answer:

Area of background without flower bed = 575 feet²

Step-by-step explanation:

Given:

Length of rectangle ground = 35 feet

Width of rectangle ground = 20 feet

Height of triangle bed = 10 feet

Base of triangle bed = 25 feet

Find:

Area of background without flower bed

Computation;

Area of background without flower bed = Area of rectangle - Area of triangle

Area of background without flower bed = [l x b] - (1/2)(b)(h)

Area of background without flower bed = [35 x 20] - (1/2)(25)(10)

Area of background without flower bed = 700 - 125

Area of background without flower bed = 575 feet²

Answer:

125 for the backyard with the flower bed, and the backyard that does not include the flower bed is 575 square feet :)

Answer:

x=34

Step-by-step explanation:

Again we are given an angle's ( x to be more specific )  opposite side length and the adjacent side length so we will use trig ratio tangent

Recall that tan = opposite over hypotenuse

[tex]tan(x)=\frac{29}{43}[/tex]

* multiply each side by the inverse of tan ( [tex](tan)^-^1[/tex] )

[tex]tan(x)*tan^-^1=x\\tan^-1*\frac{29}{43} =33.99645915\\x=33.99645915[/tex]

Finally we round to the nearest tenth of a degree and get that x = 34

C) 9 7/8 - (- 2 4/5) - (- 1/2) =

= 9 7/8 + 2 4/5 + 1/2 (F)

D) - (- 9 7/8 + 2 4/5) - 1/2) =

= 9 7/8 - 2 4/5 - 1/2 (F)

E) 9 7/8 - (- 2 4/5 - 1/2) =

= - 7/8 + 2 4/5 + 1/2 (F)

Answer:

12 7/40

Step-by-step explanation:

9 7/8 = 9 35/40

2 4/5 = 2 32/40

add:  11 67/40

67/40 = 1 27/40

11 + 1 27/40 = 12 27/40

12 27/40 - 20/40 = 12 7/40

Answer:

C.72

Step-by-step explanation:

angle XYZ is an inscribed angle and arc XZ is the arc it intercepts

If you didn't know the measure of an inscribed angle is equal to half the measure of its arc it intercepts or an intercepted arc equals twice the measure of its inscribed angle

Hence, angle XYZ * 2= arc XZ

If Angle XYZ = 36

then 36 * 2 = arc XZ

36 * 2 = 72

hence the answer is C

The measure of arc is 72 degree, the correct option is C.

An arc is formed by two radii and their intercepted part on the circumference.

According to the theorem of arc and subtended angles, the central angle subtended by the arc is double the angle subtended by it on the circumference.

The angle subtended by arc XZ on the circumference is 36 degree.

The angle subtended by the arc at the center is = 2 * 36 = 72 degree.

The arc subtended by the arc at the center of the circle is the measure of the arc.

Answer:

21.75u2

Step-by-step explanation:

first use pythag for this

use rule c2=b2+a2

reverse the rule so that

b2=c2-a2

b2=100-81

b2=19

b=4.35

how u got the height of the triangle

use formula bh/2

10x4.35/2

=43.5/2

=21.75u2

Answer: A=750 +75*t

B=900 +25*t

There would be 975 students in each high school in year 3 when they are expected to have the same number of students.

Step-by-step explanation:

A = B

750 +75*t=900 + 25*t

Solving:

75*t -25*t= 900 - 750

50*t= 150

t=3

This indicates that in year 3 both High Schools are projected to have the same number of students. To get that amount, you simply replace this value in the expressions:

A=750 +75*t= 750 +75*3= 975

B=900 + 25*t=900 + 25*3= 975

There would be 975 students in each high school in year 3 when they are expected to have the same number of students.
