Answer:
Step-by-step explanation:
Y's minus y's and x's minus x's.
9-5= 4
8-2= 6
These are the dimensions for your rectangle. Multiply them together.
4*6= 24
Your area is 24ft^2
W-13=15|+13
w=15+13
x=28
<em>Answer: w=28</em>
Answer:
-2-2√3, -2+2√3
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:
x(-4-x) = -8
-4x -x^2 = -8 . . . . . eliminate parentheses
x^2 +4x = 8 . . . . . . multiply by -1
x^2 +4x +4 = 12 . . . add 4 to complete the square
(x +2)^2 = 12
x +2 = ±√12 = ±2√3
x = -2±2√3
The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.
