Answer:

Width = 9 yds

Length = 28 yds

Step-by-step explanation:

Width = x

Length = 2x + 10

Area is 252 yd²

x(2x + 10)  = 252

2x² + 10x - 252 = 0

2 (x + 14) (x - 9) = 0

(x + 14) (x - 9) = 0

x = - 14 or x = 9

Width = 9 yds

Length = 2x9 + 10 = 28 yds

Answer:

Width = 9 yds

Length = 28 yds

pls make this the brainliest

Step-by-step explanation:

Width = x

Length = 2x + 10

Area is 252 yd²

x(2x + 10)  = 252

2x² + 10x - 252 = 0

2 (x + 14) (x - 9) = 0

(x + 14) (x - 9) = 0

x = - 14 or x = 9

Width = 9 yds

Length = 2x9 + 10 = 28 yds

hope this helps

3 - x/2 = 6 (Solve each equation) Check your answer
Yanka [14]
Answer to question
3-x/2=6
Subtract 3 from both sides
-x/2=3
Multiply 3 by -2
Final Answer: x=-6

Work check
3-x/2=6
Substitute -6 for x since you solved for x in the last equation
3-(-6)/2
Convert 3-(-6/2) to 3+6/2
3+6/2
Divide 6 by 2
3+3
Add
Final Answer: 6 (This 6 is the same 6 we used to solve for x in the first equation).

Assume that all triangles have interior angles less than 90°.A surveyor sights on a survey marker that is 132.3m distant. She ne
Vadim26 [7]

Answer:

  85.9 m

Step-by-step explanation:

The law of sines can help figure this.

The remaining angle in the triangle is ...

  180° -75° -68° = 37°

This is the angle opposite the leg from the surveyor to the second marker. Referencing the attachment, we have ...

  b/sin(B) = c/sin(C)

  b = sin(B)·c/sin(C) = 132.3·sin(37°)/sin(68°) ≈ 85.873 . . . meters

The surveyor is about 85.9 meters from the second marker.

What is the range of the function f(x) = 4x + 9, given the domain D = {-4, -2, 0, 2}?
anyanavicka [17]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f( - 4) = 4( - 4) + 9 =  - 7

_________________________________

f( - 2) = 4( - 2) + 9 = 1

_________________________________

f(0) = 4(0) + 9 = 9

_________________________________

f(2) = 4(2) + 9 = 17

_________________________________

Thus ;

R = { - 7 , 1 , 9 , 17 }

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

The correct answer is (( D )) .

Answer:

The National Academy of Sciences has established the Acceptable Macronutrient Distribution Range (AMDR), which are dietary guidelines regarding the acceptable range of certain nutrients (such as fat, carbohydrates and protein) in our everyday diet. According to the AMDR, 45-65% of our everyday calorie intake should come from carbohydrates. Therefore, 1125 [(2500*45)/100] to 1625 [(2500*65)/100] kilocalories should come from carbohydrates.

A woman spent two thirds of her money she lost two thirds the remainder and then had $4 left how much money did she start with
Lisa [10]

Answer

Find out  how much money did she start with.

To proof

let us assume that the money she had be x.

As given

woman spent two thirds of her money

Money\ spent = \frac{2x}{3}

Money she had after spent two thirds of her money  = Total money - money spent

= x - \frac{2x}{3}

= \frac{1x}{3}

As given she lost two thirds the remainder

=\frac{2}{3}\times ( money\ she\ had\ after\ spending\ two\ thirds\ of\ her\ money)

= \frac{2}{3} \times\frac{1x}{3}

we get

=\frac{2x}{9}

Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder

= \frac{1x}{3} - \frac{2x}{9}

= \frac{1x}{9}

As given

she had $4 left

thus

\frac{1x}{9} = 4

x = $36

she start with $36.

Hence proved
