5/2 =(d-2)/4

\frac{5}{2} = \frac{d - 2}{4}

d = 12

Solution steps

\frac{5}{2} = \frac{d - 2}{4}

Switch sides

\frac{d - 2}{4} = \frac{5}{2}

Multiply both sides by

4

d - 2 = 10

Move

2

to the right side

d = 12

\frac{- 7}{2}

(x + 7)^{2} = - 10

2 (\frac{4}{2})^{3} - 11

x^{2} + 4 x - 20 = 0

16 + 16 x + 3 x^{2}
