<u>Answer</u>
2(l+w)
<u>Explanation</u>
Rectangle is a fore sided figure of which two opposite sides are equal.
Let its longer side be l and its shorter side be w.
Perimeter is the distance all round.
perimeter = l + w + l + w
= l+l+w+w
= 2l + 2w
= 2(l + w)
Answer:
Slope is -2
Step-by-step explanation:
Answer:
Step-by-step explanation:
V² - 2v = 3
v² - 2v - 3 = 0
v = <u>-(-2) +/- √((-2²) - 4(1)(-3))</u>
2(1)
v = <u>2 +/- √(4 + 12)</u>
2
v =<u> 2 +/- √16</u>
2
v = <u>2 +/- 4</u>
2
v = <u>2 + 4</u> v = <u>2 - 4</u>
2 2
v = <u>6</u> v = <u>-2</u>
2 2
v = 3 v = -1
Answer: x =4
Mary is 8 and John is 4
Explanation:
John = x
Mary = 5x - 12 or 2x
Solve for x
5x - 12 = 2x
-12 = -3x
X=4
Hope that helps!
