8* 10^5 is how many times greater than 8 * 10^1

For what value of x does 4x = (1/8) x + 5?

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'
