-20

You do the reverse operation on the 4. The opposite of +4 is -4. You subtract -4 on both sides so your left with m on one side and -20 on the other side. -16 - 4 = -20

The regular octagon ABCDEFGH rotates 135º clockwise about its center to form octagon A′B′C′D′E′F′G′H′. Point A′ of the image coi
pishuonlain [190]

Answer:

The point A′ of the image coincides with point D of the preimage. The point B′ of the image coincides with point E of the preimage.

Step-by-step explanation:

It is given that regular octagon ABCDEFGH rotates 135º clockwise about its center to form octagon A′B′C′D′E′F′G′H′.

It means the central angle divided in 8 equal parts. The central angle between two consecutive vertices is

\frac{360}{8}=45^{\circ}

The regular octagon ABCDEFGH rotates 135º clockwise.

A=F'

B=G'

C=H'

D=A'

E=B'

F=C'

G=D'

H=E'

Therefore the point A′ of the image coincides with point D of the preimage. The point B′ of the image coincides with point E of the preimage.

(x+4)²-x²=0 hãy tìm x
harina [27]

Answer:

<h2><em><u>I hope this helps to :)</u></em></h2><h2><em><u>If so can you mark me as Brainliest please ?</u></em></h2>

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+4)^{2} -x^{2} =0

Step 1: Simplify both sides of the equation.

(x+4)^{2} -x^{2} =0

x^{2} +8x+16+-x^{2} =0    (Distribute Law)

(x^{2} + -x^{2})+(8x)+(16)=0     (Combine Like Terms)

8x+16=0

8x+16=0\\\\

Step 2: Subtract 16 from both sides.

8x+16-16=0-16\\8x=-16

Step 3: Divide both sides by 8.

\frac{8x}{8} =\frac{-16}{8}

x=−2

<h2><em><u>Answer:</u></em></h2><h2><em><u>x=−2</u></em></h2>

7/10. Because 0.7 equals 70% . As a fraction it would be 70/100. Simplify, and you get 7/10.
