Answer:

  • 3- False,
  • 4- True

Step-by-step explanation:

<h3>Garden A</h3>

<u>Rectangle with sides</u>

  • Width ⇒ 2x - 3 feet
  • Length ⇒ 5(2x - 3) = 10x - 15

<u>Perimeter is</u>

  • 2(w + l) = 2( 2x - 3 + 10x - 15) = 24x - 36
<h3>Garden B</h3>

<u>Triangle with sides</u>

  • 5x + 5, 4x + 2, 8x - 8

<u>Perimeter is</u>

  • 5x + 5 + 4x + 2 + 8x - 8 = 17x - 1
<h3>Statement 3</h3>

<u>The difference in perimeters is the difference is fencing:</u>

  • 24x - 36 - (17x - 1) = 24x - 17x - 36 + 1 = 7x - 35

Since it is different from 7x - 37 the statement is FALSE

<h3>Statement 4</h3>

Garden A is surrounded by a path of 2.5 ft wide

It will have the perimeter added by 2.5*2*4 = 20 ft as each side is extended by 2*2.5 ft = 5ft

<u>So the perimeter is going to be:</u>

  • 24x - 36 + 20 =
  • 24x - 16

This statement is TRUE

Please help, I will give good rating and brainliest of possible!!<br> Thank you!!!!!!!!

Answer:

g(x)=x+8

Step-by-step explanation:

Translating a function up is very simple, all you need to do here is add 8.

If you want to think of it logically,

f(x)=x

the whole right side of the function here can be our output. If x is 8, then the output, or height, is also 8. if you wanted to translate that up to 10, you'd simply need to add 2 to it, meaning x+2. Then, at any given point on the function, it'd be 2 higher than it would be otherwise.

Answer:

2.

4x^2 + 4 - 5x + x - 2x^2 + 8

= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)

= 2x^2 - 4x + 12

=> D is correct

3.

2x^2 + 6x - 7x + 8 - 3x^2 + 1

= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)

= -x^2 - x + 9

=> C is correct

4.

B is correct (4 and 3)

Hope this helps!
