Move all terms to one side
4w^2 + 49 + 28w = 0
Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7
(2w)^2 + 2(2w)(7) + 7^2 = 0
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
(2w + 7)^2 = 0
Take the square root of both sides
3w + 7 = 0
Subtract 7 from both sides
2w = -7
Divide both sides by 2
<u>w = -7/2</u>
In order to create a line parallel to line “I”, rotate line “I” 180° about points “F”. This can be done clockwise or counterclockwise.
Answer:
1.) 10000, -3, 1000 ; doesn't make sense
2.) 40000, 3, 40000 makes sense
3.) 32500, 1.5, 32500 makes sense
4.) [0,+ ∞ ]
Step-by-step explanation:
1.) r(-3) = 2500 - 3*5000=10000
2.) f(3) = 25000 + 3*5000 = 40000
3.) f(1.5) = 25000 +1.5*5000= 325000
4.) # of siblings must >= 0
Step-by-step explanation:
Any known 0 number with exponent 0 is known as undefined
If 2^x = 16, then the value of x is 4
Writing separated multiplication of numbers in short form is called product of powers property
If base is negative and exponent is odd the expression has negative value
