Please Help! After one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of a new flower bed became twice the area of an old one. How long was the side of the old flower bed?​

Answers

Answer 1

The problem says we have a square flower bed to start out with.

Let's have the sides of the squares be "x". The area of this original flower bed is [tex]x^{2}[/tex].

Then, one side of the square is enlarged by 2ft, and another side 3ft. Our new flower bed dimensions are now (x+2) and (x+3). Multiply (x+2) and (x+3) to find the area, which gets you [tex]5x^{2} +6x+6[/tex].

We also know that the new area of the flower bed is twice the size of the original flower bed. Multiply the original area by 2, you get [tex]2x^{2}[/tex].

With the new area and the doubled original area, we can now make an equation: [tex]5x^{2} +6x+6=2x^{2}[/tex]

Solve for x,  you get 6.

Hope this explanation helped, maybe a bit too many details but there's your answer, 6!

Answer 2

The side length of the original bed is 6 units

Area of square

The formula for finding the area of the square is expressed as:

A = x^2

If one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of the bed becomes;

A = (x+2)(x+3)

A = x^2 + 5x + 6

If the area of a new flower bed became twice the area of an old one, then;

5x^2 + 6x + 6 = 2x^2

On factorizing, the value of x is 6 which shows that the side length of the original bed is 6 units

Answers

Answer:

$27

Step-by-step explanation:

According to your question. The complete cost was $135 for a fifteen feet long beam. If you are looking for the price per yard, a yard has three feet, therefore in fifteen feet, there are five yards.

15 divided into 3 equals 5

$135 divided into five equals $27

The Law and Order detectives enter a house at 11:30 am and found a man on the floor murdered. They take his body temperature finding to be 91.8 F. The body is taken to the morgue and at 12:30 pm the body temperature is 84.4 F. Using an exponential model for the body temperature, to the nearest minute, what time was he killed. Normal body temperature is 98.6.

Answers

Answer:

Time of murder = 10:39 am

Step-by-step explanation:

Let the equation of exponential function representing the final temperature of the body after time 't' is,

f(t) = [tex]a(e)^{nt}[/tex]

Here, a = Initial temperature

n = Constant for the change in temperature

t = Duration

At 11:30 am temperature of the body was 91.8°F.

91.8 = [tex]98.6(e)^{nt}[/tex] --------(1)

Time to reach the body to the morgue = 12:30 pm

Duration to reach = 12:30 p.m. - 11:30 a.m.

                              = 1 hour

Therefore, equation will be,

84.4 = [tex]91.8(e)^{n\times 1}[/tex]

eⁿ = [tex]\frac{84.4}{91.8}[/tex]

ln(eⁿ) = ln(0.9194)

n = -0.08403

From equation (1),

91.8 = [tex]98.6(e)^{-0.08403t}[/tex]

[tex](e)^{0.08403t}=\frac{98.6}{91.8}[/tex]

[tex]ln[(e)^{0.08403t}]=ln[\frac{98.6}{91.8}][/tex]

0.08403t = 0.07146

t = 0.85 hours

t ≈ 51 minutes

Therefore, murder was done 51 minutes before the detectives arrival.

Time of murder = 11:30 - 00:51

                          = 10:90 - 00:51

                          = 10:39 am

What is the surface area of the rectangular prism?



16 cm 2
48 cm 2
96 cm 2
80 cm 2

Answers

Answer:

Surface area = 80 cm²

Step-by-step explanation:

Surface Area of rectangular prism = 2(LW + LH + WH)

L = 4 cm

W = 4 cm

H = 3 cm

Plug in the values

Surface Area = 2(4*4 + 4*3 + 4*3) = 2(16 + 12 + 12)

Surface Area = 2(40) = 80 cm²

The following formula gives the temperature's measure in degrees Fahrenheit F, where C is the measure

Rearrange the formula to highlight the measure in degrees Celsius.

Answers

Answer:

The rearrenged formula is [tex]C = \frac{5(F - 32)}{9}[/tex]

Step-by-step explanation:

Celsius to Fahrenheit:

To realize the conversion of the temperature in degrees Celsius to degrees Fahrenheit, we use the following equation:

[tex]F = \frac{9C}{5} + 32[/tex]

Rearrange the formula to highlight the measure in degrees Celsius.

We want to find C in function of F. So

[tex]F = \frac{9C}{5} + 32[/tex]

[tex]\frac{9C}{5} = F - 32[/tex]

[tex]C = \frac{5(F - 32)}{9}[/tex]

Use a linear approximation (or differentials) to estimate the given number. (Round your answer to two decimal places.) (1.999)3

Answers

Consider the function f(x) = x ³. Since 2³ = 8 is a perfect cube that is pretty close to x = 1.999, take the linear approximation to f(x) at x = 2. It is

f(x)L(x) = f (2) + f ' (2) (x - 2)

Compute the derivative:

f(x) = x ³   →   f ' (x) = 3x ²   →   f ' (2) = 12

Then

L(x) = 8 + 12 (x - 2) = 12x - 16

Now approximate 1.999³ :

f (1.999) ≈ L (1.999) = 12•1.999 - 16 = 7.988

(Compare this to the actual value, 7.98801.)

According to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library. If 1004 people was polled, about how many were in favor of the expansion?

Answers

Answer:

Some 224 people were in favor of the expansion.

Step-by-step explanation:

Given that, according to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library, if 1004 people was polled, to determine how many were in favor of the expansion should be done the following calculation:

1/4 = 0.25

100 = 1004

22.25 = X

1004 x 22.25 / 100 = X

223.39 = X

Thus, some 224 people were in favor of the expansion.

A. Yes the polynomial is completely factored
B. No 4 can be factored from each term of the trinomial and the resulting trinomial can be factored into two binomials.
C.no 4 can be factored from each term of the trinomial
D. No the trinomial 4x^2+8x+12 can be factored into two binomials

Answers

B......……...................

No 4 can be factored from each term of the trinomial. Therefore, option C is the correct answer.

What is factorization?

The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.

The given polynomial is x(4x²+8x+12).

Here, in the trinomial 4x²+8x+12, 4 is common factor in each term.

So, group and factor out the greatest common factor (GCF), then combine.

That is, 4(x²+2x+3)

Now, x(4x²+8x+12)= 4x(x²+2x+3)

Therefore, option C is the correct answer.

242 ft²

Step-by-step explanation:

The shape can be decomposed to give us a trapezium and a rectangle

Area of the shape = area of the trapezium + area of the rectangle

✔️Area of the trapezium = ½(a + b)h

a = 14 ft

b = 20 ft

h = 13 - 7 = 6 ft

Area = ½(14 + 20)*6

Area of trapezium = 102 ft²

✔️Area of rectangle = L*W

L = 20 ft

W = 7 ft

Area = 20*7 = 140 ft²

✔️Area of the shape = 102 + 140 = 242 ft²
