Answer:
3x-15
Step-by-step explanation:
(x-5)(8-5)
(x-5)(3)
re-order
(x-5)×3
3(x-5)
Distribute
3(x-5)
3x-15
163-x=-52
first subtract 163 and you get -215
now it looks like -x=-215
then the negative signs cancel out and its now x=215
<span>A rectangle has two pairs of sides of equal length. </span>
<span>So perimeter P = 2ft + 18in + 2ft + 18in </span>
<span>The units have to be all the same to add them so.... </span>
<span>P = 2ft + 1.5ft + 2ft + 1.5 ft </span>
<span>P = 7 ft. </span>
<span>So the board would have to be 7 feet to make a 2ft x 1.5ft picture frame.</span>
