All 4 sides of a square are the same length.
If the perimeter of the square is 20-ft, then each side is 20-ft/4 = 5 ft.
If you increase the length of the square by 2-ft, then its new length is 5+2 = 7-ft.
If you decrease the width of the square by 1-ft, then its new width is 5-1 = 4-ft.
The area of the new figure is (length) x (width) = (7-ft x 4-ft) = <u>28 square feet</u>.
Answer:
You are 34 years old
Step-by-step explanation:
Because, 34-17=17
17 is half of 34.
2x+20=y
y-17=0.5y
+17 +17
y=0.5y+17
2(0.5y+17)+20=0.5y+17
y+34+20=0.5y+17
y+54=0.5y+17
y=34
Answer:
9 months
Step-by-step explanation:
$500 - $240 = $260
$260/$30 = 8.67(3s.f.) ≈ 9 months
Recheck:
Balance after 9 months = 240 + (30×9) = 240 + 270 = $510
∴ $510 > $500

Answer:
i = 2
Step-by-step explanation:
The outside factor multiplies each term in parentheses.
5(2i +4) -i = 38
10i +20 -i = 38 . . . . eliminate parentheses
9i +20 = 38 . . . . . . collect terms
9i = 18 . . . . . . . . . . subtract 20
i = 2 . . . . . . . . . . . . divide by 9
