Answer:
The answer is 9.
Step-by-step explanation:
375 multiplied by 225 is 84,375 feet is the area
Remember that the formula for the perimeter of a rectangle is:
- is the width of the rectangle
- is the length of the rectangle
Thus, in this case, you can see that we are adding two of the same monomials and two of another monomial. One monomial is and another monomial is . In this case, these monomials would fulfill the perimeter equation of a rectangle.
Applying this perimeter structure, we can find that this expression represents a perimeter equation of a rectangle with sides x + 15 and x + 5.
Answer:
(-1-√33)/2, (-1+√33)/2
Step-by-step explanation:
If one of them is x, then it satisfies ...
x + -8/x = -1
x^2 -8 = -x . . . . . multiply by x
x^2 +x = 8 . . . . . add x+8
x^2 +x + 1/4 = 8+1/4 . . . . complete the square
(x +1/2)^2 = 33/4
x + 1/2 = ±(1/2)√33 . . . . . . take the square root
x = (-1/2)(1 ± √33) . . . . . . . subtract 1/2
The numbers are approximately ...
-3.37228, 2.37228
Answer:
56
Step-by-step explanation:
So you just need to find 7 + what is equal to 63. To find this we have to do inverse operation, which means the opposite operation. So, we do 63-7 which is equal to 56. Therefore, the solution to the equation, or x is equal to 56 (C).
