The range is [4,∞)

Or from 4 to positive infinity

Or y is greater than or equal to 4

**Answer:**

x=5

**Step-by-step explanation:**

We can use proportions to solve this problem. Put the side of the small triangle over the side of the large triangle.

9 15

------ = ----------

2x-1 3x

Using cross products

9*3x = 15(2x-1)

27x = 30x-15

Subtract 30x from each side

27x-30x = 30x-30x -15

-3x = -15

Divide by -3

-3x/-3 = -15x/-3

x = 5

**Answer:**

The distance from the midpoint of the interval to either endpoint is 6 units

**Step-by-step explanation:**

**step 1**

Find the midpoint of the interval

The formula to calculate the midpoint between two numbers is equal to

substitute

**step 2**

Find the distance from the midpoint of the interval to either endpoint.

14-8=6 units

or

8-2=6 units

therefore

The distance from the midpoint of the interval to either endpoint is 6 units

Let the length be l

Then,

l *(l-3)= 88

l²-3l =88

l²-3l-88=0

l²-11l +8l -88 =0

l(l-11) + 8(l-11) =0

(l+8)(l-11)=0

As, l can't be negative, length=11cm and width=(l-3)=11-3 =8 cm
