what must be multiplied to 3x + 7y to get 9x² - 49y²?

help.​

Answer:

the function is f(x) = 7/4x - 2

therefore the average rate of change is 7/4

Answer:

128 square feet

Step-by-step explanation:

Horizontal Gray parts:

12 - 8 = 4 ÷ 2 = 2

2 * 24 = 48 * 2 = 96

Vertical gray parts:

24 - 20 = 4 ÷ 2 = 2

2 * 8 = 16 * 2 = 32

All together:

96 + 32 = 128 square feet

Answer:

b + b + h + h and since you have two of each you can say 2b + 2h.

Answer:

5(x)+2(y)=3.45

7(x)+3(y)=4.90

Step-by-step explanation:

A. 4 x 3/5 = 4/4 x 3/5 = 12/20

B. 4x4 x 1/5 = 12/5

C. 12 + 1/5 = 4 x 3 x 1/5 = 12/5

D. 4 x 5/3 = 4 x 5 x 1/3 = 20/3​

Answer:

$70 per tv

Step-by-step explanation:

if she gets $25 extra for each and her total made was $1,235 with 13 TV's  you have to multiply 25 by 13 and get 325 then subtract that from 1,235 then get 910 which is what she made with just the fixing part so you divide that by 13 and get 70.

25x13=325

1,235-325=910

910/13=70 :)

Answer:

1308

____________

The correct answer is 1308.

Answer:

15 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (9, 10)

d = [tex]\sqrt{(9-0)^2+(10+2)^2}[/tex]

   = [tex]\sqrt{9^2+12^2}[/tex]

   = [tex]\sqrt{81+144}[/tex]

   = [tex]\sqrt{225}[/tex]

   = 15

Answer:

A

Step-by-step explanation:

Given:

Length of the parallelogram = 25 feet

Width of the parallelogram = 20 feet

Perpendicular distance from the long side to the opposite long side = 18 feet.

To find:

The area of the piece of land which is a parallelogram.

Solution:

Area of a parallelogram:

[tex]Area=Base\times height[/tex]

Let the longer side, 25 feet is the base, then the height of the parallelogram is 18 feet. So, the area of the parallelogram is

[tex]Area=25\times 18[/tex]

[tex]Area=450[/tex]

Therefore, the area of the piece of land is 450 square feet.

A ≈ 473.63

Step-by-step explanation: To find the surface area for a pyramid, we can use this formula: [tex]A=lw+l\sqrt{(\frac{w}{2})^2 } +h^2+w\sqrt{(\frac{l}{y} } )^2+h^2[/tex]

Solution: [tex]10\times10+10\times\sqrt{(\frac{10}{2} } )^2+18^2+10\times\sqrt{(\frac{10}{2} } )^2+18^2=423.63[/tex]

Answer:

B. g(x) = RootIndex 3 StartRoot x minus 3 EndRoot + 4

Step-by-step explanation:

edg 2021 .. its correct

The equation that is graphed along with the parent function is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]

The parent function is a cube root function, represented as:

[tex]f(x) = \sqrt[3]{x}[/tex]

First, the parent function is horizontally shifted right by 3 units

The rule of this transformation is:

[tex](x,y) \to (x - 3,y)[/tex]

So, we have:

[tex]f'(x) = \sqrt[3]{x - 3}[/tex]

Next, the transformed function is vertically shifted up by 4 units

The rule of this transformation is:

[tex](x,y) \to (x,y+4)[/tex]

So, we have:

[tex]g(x)=\sqrt[3]{x-3} +4[/tex]

Hence, the equation is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]

Answer:

2n + 37.

Step-by-step explanation:

an = a1 + d(n - 1)

Here a1 = 39 and d = 2

an = 39 + 2(n - 1)

= 39 + 2n - 2

= 2n + 37.

Given:

AB= 20, BV=12, VA=14 and SR is a mid segment.

To find:

The lengths of SR and AR.

Solution:

SR is a mid segment. So, SR is parallel to the non-included side BV and the length of SR is half of BV.

[tex]SR=\dfrac{1}{2}BV[/tex]

[tex]SR=\dfrac{1}{2}(12)[/tex]

[tex]SR=6[/tex]

SR is a mid segment. So, it divides the included sides in two equal parts. It means R is the midpoint of VA.

[tex]AR=\dfrac{1}{2}VA[/tex]

[tex]AR=\dfrac{1}{2}(14)[/tex]

[tex]AR=7[/tex]

Therefore, the measure of SR is 6 units and the measure of AR is 7 units.

Answer: Usually the formula for the volume of a prism is V=b(h)—> In words, Volume equals base times height. This means the height 10 would replace h. —> V=b(10). Next we want to find the B in the forumla. If you notice the question says that the base is 24 square centimeters. So our new formula is V=24(10). So option C, V=24x10 is the correct answer.

Substitute the values of angles P and Q in an equation that equals 90 degrees

62° + 4x = 90°

Then isolate the variable by first subtracting 62 from both sides

62 + 4x = 90           →    4x = 28

-62           -62

Then divide both sides by 4

4x = 28               →  x = 7

Answer:

92 m

Step-by-step explanation:

Use the Pythagorean theorem to find the length of the shorter side.

Let w = length of the shorter side.

[tex]w^{2} + 30^{2} = 34^{2} \\ w^{2} + 900 = 1156\\w^{2} = 256\\w = \sqrt{256} = 16[/tex]

The perimeter is 2l + 2w = 2(30) + 2(16) = 60 + 32 = 92 m

Answer:

not a right triangle

Step-by-step explanation:

The Pythagorean Theorem states that If a triangle is a right triangle,

the hypotenuse^2 will equal to shorter^2 + longer^2

hypotenuse = 18, shorter side = 4, longer side = 17

18^2 = 4^2 + 17^2

324 = 16 + 289

324 = 305

That is false, therefore the triangle is not a right triangle
