A carpenter is making a rectangular form for a concrete pad she wants the length of the path to be 11 feet more than the width o
Basile [38]

Answer:

Length = 16 or -5 feet.

Width = 5 or -16 feet.

Step-by-step explanation:

Let the length of the concrete pad = l

Let the width of the concrete pad = w

<u>Given the following data;</u>

Area of concrete pad, a = 80ft²

Translating the word problem into an algebraic equation, we have;

l = 11 + w

<em>We know that, the area of rectangle, A = length * width</em>

A = l*w

<em>Substituting the values into the equation, we have;</em>

80 = (11 + w)w

<em>Expanding the bracket, we have;</em>

80 = 11w + w^{2}

w^{2} + 11w - 80 = 0

*Solving the quadratic equation by using factorization method*

w^{2} + 16w - 5w - 80 = 0

w(w + 16) - 5(w + 16) = 0

(w - 5)(w + 16) = 0

Width, w = 5 feet or w = -16 feet.

<em>Therefore, the width of the concrete pad is 5 feet or -16 feet.</em>

<em>To find its length, l;</em>

l = 11 + w

When w = 5 feet

l = 11 + 5

Length, l = 16 feet

When w = - 16 feet

l = 11 + (-16)

l = 11 - 16

Length, l = -5 feet.

Hence, the dimensions of the concrete pad is 16 by 5 feet or -5 by -16 feet.

HELP!!! I will give brainliest, 25 points!!
kirza4 [7]

Cards = x

Bouquets = y

They spend 2 on each card so 2x and 3.50 for each bouquet so 3.50y add those together to get the total they can spend 2x + 3.50y = 360

Then add the sales together: 6x + 8y = 900

Answer: D. 2x + 3.50y = 360; 6x + 8y = 900

Multiply the amount he earned by 8.5%

8.5% written as a decimal is 0.085.

75,000 x 0.085 = $6,375

Part B)

Subtract the amount of tax from his earnings:

75,000 - 6,375 = $68,625

Please help!!! I will give brainliest and 50 points<br><br>The question is attached below
Serggg [28]

Answer:

1 + ln 2 - ln x

Step-by-step explanation:

ln ( 2e /x)

We know that ln ( a/b) = ln ( a) - ln (b)

ln (2e) - ln (x)

We also know that ln ( a*b) = ln a  + ln b

ln ( 2) + ln e  - ln x

We know that the ln e = 1

ln 2 + 1 - ln x

Changing the order

1 + ln 2 - ln x
