Charlie is racing in a black car. It is 12 noon. He gets a 45 -mile headstart from the starting line. He then travels at a speed of 70 miles per hour. Write the equation for this scenario.

1.6 Indien \( \frac{3}{2} \) een wortel van die vergelyking \( b x^{2}-x=3 \) is, bepaal \( b \) en die ander wortel.

\( 2.1 .2 \quad 2 x ^ { 2 } - 5 x + 2 = 0 \)

? QUESTION The area of a rectangle is \( 28 \mathrm{ft}^{2} \), and the length of the rectangle is 1 ft more than twice the width. Find the dimensions of the rectangle.

\( 2.1 .3 \quad ( \frac { 1 } { 2 } ) ^ { 3 x + 1 } = 32 \)
