Answer:
Since both terms are perfect squares, factor using the difference of squares a^2-b^2=(a+b)(a-b) where a=5x and b=4y
(5x+4y)(5x-4y)
Answer:
option 1
Step-by-step explanation:
Answer: If line segment TK is a straight line then is a both median and altitude of triangle PMT.
If Tk is a straight line, then ΔTKP & ΔTKM are congruent triangle by A S A congruent. So, KP = KM {CPCT}.
Tk is a median
-6 is the rate of change.
Answer:
B. 74
Step-by-step explanation:
The surface area is just the area of the two triangular bases plus the area of the three rectangular sides.
Area of a triangle = (1/2)bh, where b is the base and h is the height. Here, b = 4 and h = 3.5. So: (1/2) * 4 * 3.5 = 7. However, we have two triangles, so we multiply 7 by 2: 7 * 2 = 14.
Area of a rectangle = bh, where b is the base and h is the height. Here, b = 5 and h = 4. So: 5 * 4 = 20. However, there are three rectangles, so we multiply 20 by 3: 20 * 3 = 60.
Now, we just add these together: 14 + 60 = 74.
Thus, the answer is B.

Actual price of the snowmobiles = $2800
Percentage of sale on the actual cost of snowmobiles = 20%
Then
Amount of sale on the snowmobile = (20/100) * 2800 dollars
= 20 * 28 dollars
= 560 dollars
So the price of the snowmobiles after discount = (2800 - 560) dollars
= 2240 dollars
Percentage of sales tax taken = 8.25%
Amount of sales tax taken = (8.25/100) * 2240 dollars
= 18480/100 dollars
= 184.80 dollars
Then
the sale price of the snowmobiles including tax = (2240 + 184.80) dollars
= 2424.80 dollars
So the price of the snowmobiles including tax after discount will be $2424.80. I hope the procedure is clear enough for you to understand.
