The length of a rectangular garden is 8 feet longer than its width. If the garden's perimeter is 188 feet, what is the area of t
NemiM [27]

Answer: The area is 2,193 square feet (2,193 ft²)

Step-by-step explanation:The rectangular garden has its sides yet unknown but what we do know is that its length is 8 feet longer than its width. If therefore the width is W, then the length would be W + 8.

The perimeter is calculated as follows;

Perimeter = 2(L + W)

We can now substitute for the values given as follows;

188 = 2(W + 8 + W)

188 = 2(2W + 8)

188 = 4W + 16

Subtract 16 from both sides of the equation

172 = 4W

Divide both sides of the equation by 4

43 = W

If the width is 43, and the length is W + 8, then length equals 43 + 8 which gives us 51

Therefore the area is calculated as follows;

Area = L x W

Area = 51 x 43

Area = 2193

The area of the rectangular garden is 2,193 square feet

MY LAST QUESTION PLEASE HELP!! IM STUPID AND I NEED THIS DONE FAST! ONE QUESTION, AT LEAST TAKE A LOOK! WILL GIVE BRAINLIEST
nika2105 [10]

Answer:

See below.

Step-by-step explanation:

The 'ac' method. here's an example:

Factor x^2 - x - 6.  

Compare with ax^2 + bx + c:

a = 1 and c = -6 so ac = -6.

b = -1 so we try  -6 = -3 *  2:

x^2 - x - 6

= x^2 - 3x + 2x - 6

Factor by grouping.

= x(x - 3) + 2(x - 3)

= (x + 2)(x - 3).

Jessica has $50 to spend on new clothes. The
tensa zangetsu [6.8K]

Answer: No

Step-by-step explanation: she has $50

To find % you would multiply the original number by the percentage.

It would be 50*0.06 (percentages are simplified by dividing it by 100)

50*0.06=3

48.20+3=51.20

So the answer would be No Jessica does not have enough to buy the jacket.
