7 0

x/x^2-9 + 1/x-3 = 1/4x-12

x/(x+3)(x-3)+1/(x-3)=1/4(x-3)

LCD: 4(x+3)(x-3)

4x+4(x+3)=(x+3)

4x+4x+12=x+3

7x=-9

x=-9/7

ivolga24 [154]

Answer: About 63 in²

Step-by-step explanation:

<u>Area of circle = π · r²</u>

  • r = radius length
  • π ≈ 3.14

<u>Area of large pizza:</u>

\pi *r^{2} =3.14*6^{2} =3.14*36=113.04

<u>Area of small pizza:</u>

\pi *r^{2} =3.14*4^{2} =3.14*16=50.24

<u>Difference in area:</u>

113.04-50.24=62.8

Is multiplying 10 to the power of 3 the same as multiplying by 10 factors of 3
andrew-mc [135]
No because since multiplying by 10³ is multiplying by 10 times 10 times 10 which equals 1000 and multiplying by 10 factors of 3 is multiplying by 3 times 3 times 3 times 3…….for 10 times equals 59049
