Given:

2(x + 5)-7= 3(x - 2)

To Find:

• Value of x

Solution:

⇒ 2(x + 5)-7= 3(x - 2)

⇒ 2x+10-7= 3x - 6

Rearranging the like terms,

⇒ 3x-2x = 10 + 6-7

⇒x=16-7

⇒x=9

Verification:

⇒ 2(x + 5)-7= 3(x - 2)

Putting x = 9,

⇒2(9+5)-7= 3(9 - 2)

2(14)-7= 3(7)

⇒28-7=21

⇒ 21 = 21

→ LHS = RHS

Ricardo has a square hot tub. He wants to build a square pool next to it that is a dilation of the hot tub using a scale factor
PilotLPTM [1.2K]

Answer:

The length of one side of the hot tub is 4.8ft

Step-by-step explanation:

Given

Shape: Square

k = 5 -- scale factor

B'C' = 24

Required

Side length of ABCD (the hot tub)

From the question, we understand that

ABCD \to D_5 \to A'B'C'D  ABCD dilated by 5 to A'B'C'D

This implies that:

BC * 5 = B'C' i.e. the sides of ABCD is multiplied by 5 to get A'B'C'D

So, we have:

BC * 5 = 24

Divide by 5

BC = 4.8

Is anyone able to figure this out, I can't do this
katrin [286]

Answer:

C. √2 - 1

Step-by-step explanation:

If we draw a square from the center of the large circle to the center of one of the small circles, we can see that the sides of the square are equal to the radius of the small circle (see attached diagram)

Let r = the radius of the small circle

Using Pythagoras' Theorem a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

to find the diagonal of the square:

\implies r^2 + r^2 = c^2

\implies 2r^2 = c^2

\implies c=\sqrt{2r^2}

So the diagonal of the square = \sqrt{2r^2}

We are told that the radius of the large circle is 1:

⇒ Diagonal of square + r = 1

\implies \sqrt{2r^2}+r=1

\implies \sqrt{2r^2}=1-r

\implies 2r^2=(1-r)^2

\implies 2r^2=1-2r+r^2

\implies r^2+2r-1=0

Using the quadratic formula to calculate r:

\implies r=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

\implies r=\dfrac{-2\pm\sqrt{2^2-4(1)(-1)}}{2(1)}

\implies r=\dfrac{-2\pm\sqrt{8}}{2}

\implies r=-1\pm\sqrt{2}

As distance is positive, r=-1+\sqrt{2}=\sqrt{2}-1  only
