10 and the math be hide it is 600/60=10
<span>I believe you MEANT 8/(x^2-25)+9/(x-5) Parentheses in this format are important...the way you typed it means (8/x^2)-25+(9/x)-5 which I doubt you mean. Anyway.
If you factor the first denominator you will see that it is equal to (x+5)(x-5). Division by zero has no meaning so x cannot equal -5 or 5.
If we multiply the second fraction by (x+5) we will have a common denominator of (x^2-25) for the entire equation leaving us with:
(8+9x+45)/(x^2-25)
(9x+53)/(x^2-25)
The second problem is worked in exactly the same way, notice that there is no "solution" as there is no equal sign. This is an "expression" not an "equation".</span>
The surface area of the square bottom = L x W = 7 x 7 = 49 cm^2
The area for one of the triangles = 1/2 x base x height = 1/2 x 7 x 9 = 31.5 cm^2
There are 4 triangles, the total area for the triangles = 31.5 x 4 = 126 cm^2
Total area = base + triangles = 49 + 126 = 175 cm^2
Answer:
32.5 and 30
Step-by-step explanation:
I counted the unit squares one by one.
Hope this helped! :)
<span>y=4 (x-2)^2-1
y = 4(x^2 - 4x + 4) -1
y = 4x^2 - 16x + 16 - 1
y = 4x^2 - 16x + 15
answer
</span><span>standard form
</span>y = 4x^2 - 16x + 15
