(a(1-0.2^4))/(1-0.2)=671

\frac{a ( 1 - 0. 2 ^{4} )}{1 - 0.2} = 671

a = 537.66025 \dots

Solution steps

\frac{a ( 1 - 0. 2 ^{4} )}{1 - 0.2} = 671

Multiply both sides by

1 - 0.2

0.9984 a = 536.8

Divide both sides by

0.9984

a = 537.66025 \dots

- 4 (x + 2) > 3 x + 20

x^{2} - 5 x + 2 < 8

(- 25)^{\frac{1}{2}}

\frac{1}{3} (3)^{2}

2 x + 7 < 3 + 4 x
