Answer:

x^3-2x^2-13x+6

Step-by-step explanation:

We are to simplify the expression (x+3)(x^2−5x+2). This is as shown;

(x+3)(x^2−5x+2)

Expand

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

= x^3 - 5x^2+2x+3x^2-15x+6

Collect the like terms

= x^3 - 5x^2+3x^2+2x-15x=6

= x^3-2x^2-13x+6

This gives the required expression

Answer:

4 months

Step-by-step explanation:

Let

x = number of months

Workout plus = 100 + 30x

Fit works = 20 + 50x

After how many months will memberships to both gyms cost the same amount?

Equate the cost of both gyms

Workout plus = Fit works

100 + 30x = 20 + 50x

100 - 20 = 50x - 30x

80 = 20x

x = 80/20

x = 4 months

After 4 months, memberships to both gyms cost the same amount

x = 13, y = 18

hope this is right

Answer:

x=−3 and y=−2

Step-by-step explanation:

-5x+4(-2x-8)=7

-13x-32=7

-13x-32+32=7+32

-13x=39

divide both sides by -13

x=-3

substitute x for -3

-2(-3)-8= -2

y= -2

Answer:

Step-by-step explanation:

Y = 1/5 x + 14 where b = 7

Result:

x + 70 = 5 Y

Geometric figure:

line

Alternate forms:

x = 5 Y - 70

x - 5 Y + 70 = 0

Real solution:

Y = x/5 + 14

Solution:

Y = x/5 + 14

Integer solution:

x = 5 n, Y = n + 14, n element Z

Solution for the variable x:

Answer:

Step-by-step explanation:

Given,

Length of the bedroom = 13 feet

Width of the bedroom = 9 feet

Therefore,

First Case:

Area of the bedroom = Length × Width

= 13 feet × 9 feet

= 117 sq. ft.

Second Case:

Perimeter of the bedroom = 2(Length + Width)

= 2 (13 + 9) feet

= 2 × 22 feet

= 44 feet

Hence,

Required area of the bedroom is 117 sq. ft. and perimeter of the bedroom os 44 feet (Ans)

Answer:

[tex]y = \frac{1}{2} x+5[/tex]  

Step-by-step explanation:

1) First, find the slope of the line that passes between the two points. Substitute the x and y values of (2,6) and (-8,1) into slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Then, solve:  

[tex]m = \frac{(1)-(6)}{(-8)-(2)} \\m = \frac{1-6}{-8-2} \\m = \frac{-5}{-10} \\m = \frac{1}{2}[/tex]

So, the slope is [tex]\frac{1}{2}[/tex].

2) Now, write the equation of the line using the point-slope formula, [tex]y-y_1 = m (x-x_1)[/tex]. Substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].

Since [tex]m[/tex] represents the slope, substitute [tex]\frac{1}{2}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of one of the given points into the formula as well. (Any of the two will do. Either choice will represent the same line. I chose (2,6).) Then, isolate y to put the equation in slope-intercept form and find an answer:

[tex]y-6 = \frac{1}{2} (x-2)\\y-6 = \frac{1}{2} x-1\\y = \frac{1}{2} x+5[/tex]

Answer:£2121.8

Step-by-step explanation:

Given

Principal money [tex]P=[/tex]£2000

rate of interest is  [tex]R=3\%[/tex]

time period [tex]T=2\ yr[/tex]

The amount by compound interest is given by

[tex]A=P[1+\frac{R}{100}]^T[/tex]

Putting values

[tex]\Rightarrow A=2000[1+0.03]^2\\\Rightarrow A=2121.8[/tex]

So, after two years it will be £2121.8

Answer:

4.2 inches

Step-by-step explanation:

Basketball rim:

diameter = 18 inches

r = 18/2 = 9 inches

Ball:

Circumference of ball = 30 inches

2πr = 30 inches

[tex]2*3.14*r = 30\\\\r = \frac{30}{2*3.14}\\\\r = 4.8 inches[/tex]

Distance between the ball and the rim in a shot when the ball goes exactly in the center of the rim = radius of the rim - radius of the ball

   = 9 - 4.8

   = 4.2 inches

Answer:

The number 173 or 1,173?

1,173 x 1,173 = 1,375,929

Since all sides are equal in a square, one given length would be all the side lengths since all sides are equal in a square.

If the side length was 173 then:

173 x 173 = 29,929

Answer:

1 day =   221 hot coffee cups and 117 iced coffee cups

2 day = 247 hot coffee cups and 234 iced coffee cups

Step-by-step explanation:

A new coffee shop sold 468 cups of hot coffee and 351 cups of iced

coffee during its first two days. The ratio of cups of hot coffee sold to cups of

iced coffee sold on the first day was 17 : 9. On the second day, the shop sold

twice as many cups of iced coffee as the first day. The ratio of cups of hot

coffee sold to cups of iced coffee sold on the second day was 19 : 18.

a) How many cups of each type of coffee did the shop sell the first day?

Let  cups of hot coffee be denoted by x

Then

17x+ 19x= 468

or

36x= 468

x= 13

On the first day the number of hot coffee cups sold are 17y or 17*13=  221 cups.

On the second day the number of hot coffee cups sold are 19y or 13*19=  247 cups.

Similarly Let  cups of iced coffee be denoted by  y

Then

9y+18y= 351

27y= 351

y= 351/27= 13

On the first day the number of iced coffee cups sold are 9y or 13*9=  117 cups.

On the second day the number of iced coffee cups sold are 18y or 13*18=  234 cups.
