Answer:
3
Step-by-step explanation:
3/3=1 which is smaller then 2
Solve for x over the real numbers: by completing the square:
5 x^2 - 30 x = 5
Divide both sides by 5:
x^2 - 6 x = 1
Add 9 to both sides:
x^2 - 6 x + 9 = 10
Write the left hand side as a square:
(x - 3)^2 = 10
Take the square root of both sides:
x - 3 = sqrt(10) or x - 3 = -sqrt(10)
Add 3 to both sides:
x = 3 + sqrt(10) or x - 3 = -sqrt(10)
Add 3 to both sides:
Answer: | x = 3 + sqrt(10) or x = 3 - sqrt(10)
135 miles / 2.5 hours = 54 mph
54 mph x 4 hours = 216 miles
Answer:
Step-by-step explanation:
<u>Set inequality and solve:</u>
- 25x ≥ 350
- x ≥ 350/25
- x ≥ 14
Correct choice is C
6 x 7 + 9 x 7
Explanation:
Ok so if you separate that figure into two shapes, you will have 2 rectangle.
Its kinds too long to explain, but just know that to find the formula of a rectangle is length x width.
So, find the area of the rectangle on the left first:
The width of the rectangle on the left is 6
The length is 7
Multiply 6 x 7
Next, find the area of th rectangle on the right:
The length is 9
The width is 7
Multiply 9 x 7
Since this is originally one figure, we do this:
6 x 7 + 9 x 7
