expand 1400(7-x)+2800sqrt(9+x^2)

expand

1400 (7 - x) + 2800 9 + x^{2}

9800 - 1400 x + 2800 9 + x^{2}

Solution steps

1400 (7 - x) + 2800 9 + x^{2}

Apply the distributive law:

a (b - c) = ab - a c

1400 (7 - x) = 1400 \cdot 7 - 1400 x

= 1400 \cdot 7 - 1400 x + 2800 9 + x^{2}

Multiply the numbers:

1400 \cdot 7 = 9800

= 9800 - 1400 x + 2800 9 + x^{2}

6 (x + 3 = 5 x + 1)

\frac{d}{d t} ((s) (5 t^{2} - 3 sec (t) + 2 e^{t}))

\frac{( 2 x + 5 ) ^{3}}{2}

(3 x^{2} y + 3 x) d x + (x^{3} + 2) ey d y

\frac{1}{3} (\frac{6}{5} x - 3)
