Answer: 7.5
Form your proportion. Let x be the width of QRST.
Length of ABCD Length of QRST
----------------------- = -------------------------
Width of ABCD Width of QRST
8/5 = 12/x
Solve for x by cross-multiplying.
(8)(x) = (12)(5)
8x = 60
x = 7.5
Answer:
<h2>5,040 I'm sure that's answer thank you</h2>
The first step for solving this expression is to distribute
through the first set of parenthesis.
× (x - 9)
Now use the FOIL method to multiply each term in the first parenthesis by each term in the second parenthesis. This will look like the following:
x × x -
x × 9 -
x -
× (-9)
Remember that multiplying two negatives together equals a positive,, so the expression changes to:
x × x -
x × 9 -
x +
× 9
Calculate the product of all of the sets of multiplication to make the expression become:
x² -
x -
x +
Lastly,, calculate the difference of -
x -
x to find your final answer.
x² -
x +
