NEED HELP NOW Find the area of a rectangular garden that has a width of 4x – 6 and a length of 2x + 4.

Answers

Answer 1
Answer:

The area of rectangular garden is 8 x^(2)+4 x-24

Solution:

Given that a rectangular garden has width = 4x - 6

Length of rectangular garden = 2x + 4

To find: area of rectangular garden

The area of rectangle is given as:

\text {area of rectangle }=\text { length } * \text { width }

Substituting the values in given formula,

\begin{array}{l}{\text { area of rectangle }=(2x+4) *(4x-6)} \n\n {=8 x^(2)-12 x+16 x-24} \n\n {=8 x^(2)+4 x-24}\end{array}

Thus the area of rectangular garden is 8 x^(2)+4 x-24

Answer:

#2 Karen is 7 years old

#3 Amy will be 31 years old in 10 years

Step-by-step explanation:

2#:

  1. b+3=2(k+3)
  2. b-2=3(k-2)
  3. 2b+1=5k
  4. 2b-5k=-1
  5. b-2k=3
  6. 2b-4k=6
  7. 2b-4k-(2b-5k)=6-(-1)
  8. k=7

3#:

  1. a+1=2(s-5)
  2. a+s+8=45
  3. a-2s=-11
  4. a=37-s
  5. 37-3s=-11
  6. -3s=-48
  7. s=16
  8. a=37-16
  9. a=21
  10. 21+10=31

how to find the depth of a rectangular prism?? I already have the length, width ad the volume. But I'm confused on how to find the height?

Answers

You have everything you need to find it.
Look at this for a second:

Volume = (length) x (width) x (height)

Divide each side of this equation by (length) x (width), and you have

Height = (Volume) / (length x width)

You have all the numbers on the right side, so you can easily find the height.


set up your equation

Length x Width x Height = Volume

plug in the known factors and simplify L x W x H. Divided the numerical value on both sides. you are left with H

kelly is 66 inches tall. Lucas is 72 inches tall. What is the ratio of Lucas's height to Kelly's height in simplest form? (: also, explain please!

Answers

Just divide Lucas's height by Kelly's height.
72/66
The GCF is 6 so divide both by 6
12/11
That's the answer :)
72/66 greatest common factor is 6 so iffy would be 12/11 which is your answer.:)

Hello there! :)

Answer:(1)/(343)

*The answer must have a fraction.*

Step-by-step explanation:

Lesson: Zero and Negative Exponents.

Distributive property: a(b+c)=ab+ac

First, you apply exponent rule.

a^b*a^c=a^b^+^c

7^-^3

(1)/(7^3)=7^3=7*7*7=343

Final answer: (1)/(343)

Hope this helps!

Thanks!

a painter has a 24-foot ladder that he is using to paint a house for safety reasons, the ladder must be placed at least 8 feet from the base of the side of the house. to the nearest tenth of a foot. How high can the ladder safely reach?

Answers

The ladder can safely reach up to 22.6 ft.

What is Pythagoras theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Given that, a ladder has a length of 24 ft, and it should be placed at least 8 feet from the base of the side of the house.

We need to find how high can the ladder safely reach,

Using the Pythagoras theorem here,

24²-8² = 576-64 = 512 ft

Hence, the ladder can safely reach up to 22.6 ft.

#SPJ3
this is a pythagorean theorem problem. 24 is the whole ladder, and if you draw it out, is a hypotenuse. 8 is a leg. a^(2) + b^(2) = c^(2). so 8^2 + b^2 = 24^2

b^2 = 512, so b = sqrt(512) = 22.6
