Should be a!
26^2 - 22^2 = 192, take the sqrt of that C:
The answer
<span>the true answer is A) 4x^2+52x+165=320; x = 2.5
proof:
since </span><span>they want to limit its area to 320 in^2
x must be equal 2.5, because </span>4.(2.5)^2+52(2.5)+165= 25+130+165=320;
the main rule of the area of a triangle is
A= (base x height )/2
let be b the base and h the height
so h=20- 6b
so 50= b x( 20-6b) /2, implies 100/b = 20 - 6b
if b=x, we have 100= 20x -6x² this is equivalent to 6x² - 20x = -100
so the answer is
<span>D) None of the choices are correct.
</span>
<span>the largest dimensions that can be used for the fountain are
</span>
<span>B) x^2+8x+16=800
C) x^2+16=800
</span>
proof
x^2+8x+16=x^2+8x+4², 4² is the area of the square fountain, and x^2+8x should be the remaining of the area, t<span>he total space that the fountain and sidewalk can use is 800, it is less than 800 ft^2.
</span>Use the same method for. x^2+16=800
I think the answer to this is d hope it helps
The answer would be 108 ft^2
Answer:
1. Felix can easily determine that the panaview model has a lower price = Value of money
2. Felix saved $30 per week = Resource gathering
3. Felix pays $140 for the Blu-Ray = Medium of exchange
Step-by-step explanation:
1. The price of each blu-ray is notices by Felix as he can easily see the value and compare prices to drive his decision
2. The resource's needed to for obtaining the value which Felix desired is gathered.
3. Exchange of money for desired value or valuable
