Answer: the length is 15 m and the width is 5 m
Step-by-step explanation:
Let L represent the original length of the rectangle.
Let W represent the original width of the rectangle.
The length of a rectangle is three times it's width. This means that
L = 3W
If the width is diminished by 1 m and length is increased by 3 m, the area of the rectangle that is formed is 72 m². This means that
(L + 3)(W - 1) = 72
LW - L + 3W - 3 - 72 = 72 + 3
LW - L + 3W = 75 - - - - -- - - - - - 1
Substituting L = 3W into equation 1, it becomes
3W × W - 3W + 3W = 75
3W² = 75
W² = 75/3 = 25
W = √25 = ±5
The width cannot be negative. Therefore, the width is 5 m
L = 3W = 3 × 5 = 15 m
Go up. This is because the stock price is going up.
Answer:
G(62.5)
Step-by-step explanation:
30/48 × x/100=62.5/2.08
to solve x
100÷48=62.5(x)
62.5(x)×30=62.5
Answer is F
(g + f)(x)
g(x) + f(x)
x - 1 + x^2 + 4
x^2 + x + 3
(g - h)(x)
g(x) - h(x)
3x + 1 - (2x - 2)
3x + 1 - 2x + 2
x + 3
Answer:
2 9/10
Step-by-step explanation:
1)Turns 5 4/5 into an improper fraction which would be 29/5 divide 29/5 by 2/1
2) Multiply 29/5 by 1/2 which will give you 29/10
30 Turn 29/10 into a mixed fraction which should be 2 9/10
