Answer:

x= 5/2, x= -3

4x^2+2x-30=0; Factor that without the 0. Then you get 2 (2x-5) (x+3)=0.

2x-5=0 x= 5/2

x+3=0 x= -3

Hope this helps! :D

The answer is x = 11

first you multiply the numbers
0= 8 + 2x- 30

then you calculate that difference
0= -22+ 2x

then move variable to the left
-2x= -22

divide
x= 11

Uncle Bill has planted fruits in the farm and 7/12 is watermelon.2/3 of the watermelon section is ruined from the storm.The rest

inessss [21]

The fraction of his farm which isn’t ruined is 11/18

<h3>Fractions and proportion</h3>

Fractions are written as a ratio of two integers. The given question will be solved using the method of proportion.

If Uncle Bill has planted fruits in the farm and 7/12 is watermelon, and 2/3 of the watermelon section is ruined from the storm, the fraction ruined from the storm is;

Fraction ruined from the storm = 2/3* (7/12)

Simplify to its lowest term to have:

Fraction ruined from the storm = 7/18

Determine the fraction of the firm that is not ruined

Fraction not ruined = 1 - 7/18

Fraction not ruined = 11/18

Hence the fraction of his farm which isn’t ruined is 11/18 if uncle Bill has planted fruits in the farm and 7/12 is watermelon.
