Area of a rectangle of length L and width W is A = LW.

Here, A = 60 ft^2 = (12 ft)(2x-3  ft).  Let's find the values of x for which the area =60 ft^2, and then the values of x for which the area is greater than 60 ft^2.

60 = 12(2x-3) becomes 5 = 2x - 3 after dividing both sides by 12.

Adding 3 to both sides of this last equation results in 8 = 2x, so x = 4.

Does (12 ft)(2[4 ft] - 3) = 60?  Does (12 ft)(5 ft) = 60 sq ft?  YES.

The area of this rectangle will be greater than 60 sq ft if x>4 ft.  (answer)

I’ve saved £264. I will spend 3/12 of this. How much do I have left?
lara [203]
Hi there! The answer is £198.

If you spend 3 / 12 of a certain amount of money, you have 9 / 12 of the money left.

Simplify the fraction.
9 / 12 = 3 / 4.

To find the amount of money left, we multiply this factor by 264. We get the following
£264 × 3/4 = £264 × 0.75 = £198

Therefore the answer is £198

A recipe calls for 4 cups of flour. Lauren wants to make 20% more servings than the recipe makes. Which expression represents ho
ale4655 [162]
C. 6/5 * 4

6/5 = 1.20 where .20 represents the 20% increase in serving.

1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%

4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups

the length of a rectangle is 2 times in width if the perimeter of the rectangle is 36 in find its length and width​
Basile [38]

Answer:

Length=12 inches Width=6 inches

Step-by-step explanation:

X can stand for the width. 2x can stand for the length since it is twice the width. The perimeter would then equal 6x. 6x is equal to 36. Divide by 6 to isolate x. X equals 6 inches. So twice the width would be 12 inches.
