Answer:
226.5
Step-by-step explanation:
area=area of larger rectangle - area of smaller rectangle
Area= (16×17) - (6.5×7)
=226.5
Answer:
B
Step-by-step explanation:
slope formula
we have the two points
(2,4) (3,7)
which means the slope for line m is 3x
our equation so far looks like this
y=3x+b
plug in a set of numbers to solve for b
let's use (2,4)
4=3(2)+b
4=6+b
b= -2
which means our equation is
y= 3x-2
which is equal to
2= 3x-y
the only answer is then B
3.6 > 0.94 Hope this helps.
Answer:
2010
Step-by-step explanation:
If the numbers are x and y, you have ...
x +y = 97
x -y = 37
Adding these two equations gives ...
2x = 134
x = 67
y = 67 -37 = 30
The product is then ...
xy = (67)(30) = 2010

<em>Alternate solution</em>
There is no need to find the actual numbers. We can go directly to their product.
(x+y)² = x² +2xy +y² = 97² = 9409
(x-y)² = x² -2xy +y² = 37² = 1369
Subtracting the second equation from the first gives ...
4xy = 9409 -1369 = 8040
xy = 8040/4 = 2010
Of course the difference of squares can be factored, so we could compute ...
(97² -37²)/4 = (97 +37)(97 -37)/4 = 134(60)/4 = 134(15) = 2010
