On a test, wrong answers are worth -5.25 points and right answers are worth 3.5 points. So far, Marshall has one right answer an

Over [174]

Answer:

Marshall's current score is - 1.75 points

Step-by-step explanation:

From the question,

Wrong answers are worth -5.25 points and right answers are worth 3.5 points.

Currently, Marshall has one right answer and one wrong answer.

To determine Marshall's current score, we will multiply the number of right answers has by 3.5 points and multiply the number of wrong answers by -3.5 points and then add the results.

Number of right answers = 1

Number of wrong answers = 1

For the right answer, he has

1 × 3.5 points = 3.5 points

For the wrong answer, he has

1 × - 5.25 points = -5.25 points

Hence, Marshall's current score is

3.5 points + ( -5.25 points) = 3.5 points - 5.25 points

= - 1.75 points.

Hence, Marshall's current score is - 1.75 points.

Which expression is equivalent to StartRoot 120 x EndRoot?.

Irina-Kira [14]

Here for 120, the expression for the start root and end root is given

$\sqrt{120} =2\sqrt{30}$

<h3>What will be the expression for start root and enroot of 120?</h3>

Here we need to find $\sqrt{120}$

By simplifying the given expression, we get:

$120=2\times2\times2\times3\times5$

$120=(2^{2} )\times3\times5$

by taking square roots on both sides we get

$\sqrt{120} =2\sqrt{30}$

Thus for 120, the expression for the start root and end root is given $\sqrt{120} =2\sqrt{30}$
