The answer is 22,440......4 miles is 21,120 feet....1/4 of a mile is 1,320 feet.... so when you add em up you get 22,440 feet
Quotient rule says we can divide 192 and 3 because they are both under the radical. This gives us the square root of 64.
We can also divide x^3 and x to get x^2.
The square root of 64x^2 is 8x
Answer:
77
Step-by-step explanation:
Rate as BRAINLIEST
x + 9y
we plug in x and y
5+9(8)
=5+72
= 77
Answer:
7 + 7n
Explanation:
Seven more (7 plus) the product of 7 and a number (seven times n) = 7 plus 7n
Answer:
11 meters
Step-by-step explanation:
Lets say that w = width of the rectangle, to start. If the length of the rectangle is 3 meters greater than 2 times the width, the length of the rectangle is equal to 3 + 2w.
The perimeter of the rectangle is 2 * length of rectangle + 2 * width of the rectangle. With the perimeter being equal to 30 and width being w and length being 2w+3:
The perimeter of the rectangle is 2(w) + 2(2w+3) = 30.
We first need to find out w first, which will give us the width of the rectangle. Taking it step by step, we get:
2w + 4w + 6 = 30
6w + 6= 30
6w = 24 which is done by subtracting both sides by 6 to put the variables on one side and the values on the other side
w = 4 which is done by dividing 6 on both sides
Ultimately, this gets width to be 4 meters. Now that we found the width, we need to plug w = 4 into the equation we set up for length which is 2w+3.
That being said, the ANSWER is:
length of rectangle = 2(4)+3 = 11 meters
Hope this helps! :)
