Answer:

2x²+7x-4

Step-by-step explanation:

2x²+8x-x-4

2x²+7x-4

Answer:

2x² + 7x - 4

Step-by-step explanation:

(2x + 1)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 4) - 1 (x + 4) ← distribute parenthesis

2x² + 8x - x - 4 ← collect like terms

= 2x² + 7x - 4

Answer:

it rose three eighths of a pound

Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.

X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2

X = [1 +/- sqrt(97)]/2

10c - 5

Step-by-step explanation:

" the product" tells you you're multiplying 10 and c, and "5 less" means subtracting 5 from the other part of the expression.

Answer: son, estoy, estas, es, son, estamos, son, estan

Step-by-step explanation:

If it is talking about someone else then try to use, son. Like the first one. For words for yo use words like estoy. I don´t really know how to explain them but they make sense.

Answer:

Step-by-step explanation:

So first we distribute -12 to 6 making that -72 then we distribute the -12 to the 4 making that -48.

So we have -72+-48 = -72 - 48 = -120

It is important to know that the answer is not -120 (10)(-12) = -120

because that is not the distributive property.

Hope this helps

Answer:The Cost of one rose bush is $11 and the cost of one shrub is $5

Step-by-step explanation: Well it took me 40 mins to get the answer and yes i know it shouldn't take that long but for a freshmanbut wow that was hard  , well 11 x 8 = 88 and 5 x 8 = 40 add that up 128 and for the 2nd question 11x 11= 121 then 5x 12= 60 and when you add it up you got 181 so what would the main numbers be that you used for both problems? it would be 11 for one  rose  and 5  for one shrubs. thanks for wasting my time on a hard question that took me 40 mins to answer

Answer:

assuming that you want us to add them together here's the answer i got-

5y²−3y+3

Step-by-step explanation:

let us simplify step-by-step-

4y²−2y−5+y²(−y)+8

= 4y²+(−2y)+(−5)+y²+(−y)+8

combining like terms-

=4y²+−2y+−5+-y²+−y+8

=(4y²+y²)+(−2y+−y)+(−5+8)

=5y²+−3y+3

good luck :)

i hope this helps

Answer:

  32 dm

Step-by-step explanation:

Use the formula for the area of a triangle, and solve for the unknown.

  A = 1/2bh

  200 dm² = 1/2(12.5 dm)b

  b = (200 dm²)/(6.25 dm) = 32 dm

The base of the triangle is 32 dm.

Answer:

Yes, they are proportional

Step-by-step explanation:

First, simplify each fraction

30/80 can be simplified by dividing each number by 10

30/80

= 3/8

24/64 can be simplified by dividing each number by 8

24/64

= 3/8

So, each fraction will simplify to 3/8, meaning that they are proportional.

Answer:

The first blank is 9  for 9 cucumbers

The second blank is 8 dollars

Step-by-step explanation:

We can use ratios to solve

3 cucumbers           x cucumbers

--------------------- = ----------------------

2 dollars                   6 dollars

Using cross products

3*6 = 2x

18 = 2x

Divide by 2

18/2 = 2x/2

9 =x

We need 9 cucumbers

For the third row

3 cucumbers           12 cucumbers

--------------------- = ----------------------

2 dollars                   y dollars

Using cross products

3*y = 2*12

3y = 24

Divide by 3

3y/3 = 24/3

y = 8

We need 8 dollars

The null hypothesis is : [tex]$u_1=u_2=u_3=u_4$[/tex]

Alternative hypothesis : At least one of the [tex]$u$[/tex] is not equal.

The significance level = 0.05

Analyzing the sample data:

F statistics is given by :

[tex]$F=\frac{MSB}{MSE}$[/tex]

  = 2.97

[tex]$F_{critical}=3.24$[/tex]

The P-value= 0.06

The result : Since the P-value of 0.06 is greater than the significance level (0.05), hence we fail to reject the null hypothesis.

So we cannot conclude that there is no difference between the average maximum heart rates that are achieved during the four workouts.

Answer:

[tex]VW = 50[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find VW

To find VW, we make use of the following equivalent ratios.

[tex]YX : XW = ZX : XV[/tex]

Where:

[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]

[tex]XV = XW + VW = 25 + VW[/tex]

So, we have:

[tex]14 : 25 = 42 : 25 + VW[/tex]

Express as fraction

[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]

Divide both sides by 14

[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]

Cross multiply

[tex](25 + VW) * 1 = 3 * 25[/tex]

[tex]25 + VW = 75[/tex]

Solve for VW

[tex]VW = 75 -25[/tex]

[tex]VW = 50[/tex]

Answer:

each tangent is 20.785 ft long

Step-by-step explanation:

since the tangent forms a right angle with the radius, and a line from P to O bisects the 60° angle:

tan 30° = 12/x

0.5774 = 12/x

0.5774x = 12

x = 20.785 ft

Answer:

X=4

Step-by-step explanation:

4x(x+3)=112

4x^2+12x=112

x^2+3x=28

x^2+3x-28=0

(X+7)(x-4)=0

X=-7 or x=4

Answer:

volume of cuboid =l×b×h

112in³=(x+3)×x×4

112in³/4=x²+3x

28=x²+3x

x²+3x-28=0

x²+7x-4x-28=0

x(x+7)-4(x+7)=0

(x+7)(x-4)=0

either

x=-7(rejected length or breadth or height will be always positive)

or

x=4in

value of x =4in

In order:

72 x 8 = 576

47 x 7 = 329

(7 x 3) x 7

21 x 7 = 147
