Answer:

let the equal sides of the triangle be of length "a" . let the angle between these two sides be " x ". Then drop a perpendicular from the vertex to the base. now u have 2 similar triangles .the angle between the perpendicular and one of the equal sides is now (x/2) . length of perpendicular = a cos(x/2) length of base = 2a sin(x/2) . area of triangle = (1/2) 2sin(x/2) cos(x/2) a-square

= (1/2) (sin x) a-square

Write 25x10 the power of 6 in standard from

forsale [732]

Answer:

25 * 10^6

But 10^6 is the same as multiply 10 six times, that is, 10 * 10 * 10 * 10 * 10 * 10 * 10. The result is as simple as writing 1 and six zeros, that is, counting the number of zeros I can see. So, 10^6 = 1000000.

Now, 25 * 10^6 = 25 * 1000000

The final answer is 25000000

PLEASE HELP ASAP

Wouldn’t it be 0, as that’s when their values are both equal to each other, making the equation true?

(2n^4 - 8 - 3n) - (4n^2 + 7n +4) <br> I have to simplify but don't know how to

Ahat [919]

First remove the parenthes as there is a negtive outside the second parentheses the signs of the terms inside change.

= 2n^4 - 8 - 3n - 4n^2 - 7n - 4

Now simplify like terms

= 2n^4 - 4n^2 - 10n - 12

= 2(n^4 - 2n^2 - 5n - 6)
