Answer:

$4x-3$

Step-by-step explanation:

$(7x-5) -(3x-2)$

Remove unnecessary parentheses

$7x-5-(3x-2)$

When there is a " _" in front of any expression in parentheses , change the sign of each term of the expression.

$7x-5-3x+2$

Collect Like terms by subtracting their Coefficients

$(7-3)x$

Subtract the numbers

$4x-5+2$

Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger

$-(5-2)$

Subtract the numbers

$-3$

$4x-3$

The quadrilateral shown is a rectangle. What is the measure of PR? (round to the nearest hundredth) A) 34.06 B) 37.12 C) 40.24 D

Nata [24]

Answer: OPTION B.

Step-by-step explanation:

The missing figure is attached.

For this exercise you need to use the Pythagorean Theorem. This is:

$a^2=b^2+c^2$

Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.

In this case you can identify in the figure the triangle PRS, so the diagonal PR is the hypotenuse of the triangle PRS.

Then you can say that:

$a=PR\\b=PS=17\\c=RS=33$

Therefore, knowing these values, you can substitute them into $a^2=b^2+c^2$ :

$PR^2=17^2+33^2$

Finally you must solve for PR in order to find its value. This is:

$PR=\sqrt{17^2+33^2}\\\\PR=37.12$
