Let x be the common length. Then, the sides of the triangle are x, x, and 2x-6. These three sides sum up to 22, so you have
So, the two equal sides are 7m long, and the third side is
Answer:
(3, 0 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
= - 
y = 5x² - 30x + 45 ← is in standard form
with a = 5, b = - 30 , then
= - 
= 3
Substitute x = 3 into the function for corresponding value of y
y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0
vertex = (3, 0 )
Yes because if the original price is $42 and you take off the 30% it will be 12.6 plus the sale tax rate it will be $13.10 and he will have $21.90 left

Answer:
625√2 cm
Step-by-step explanation:
The diagonal of a square is √2 times the side length, so the side length is 1/√2 = (√2)/2 times the length of the diagonal:
s = (√2)/2 × 1250 cm = 625√2 cm
The side length is 625√2 cm.

<em>Additional comment</em>
A unit square will have sides of length 1. A diagonal of the square will divide it into two right triangles, each with sides of length 1. The Pythagorean theorem tells you the length of the diagonal (d) will be ...
d² = 1² +1² . . . . . . square of hypotenuse is sum of squares of legs
d² = 2 . . . . . . . simplify
d = √2 . . . . . take square root
That is, for any square, the length of the diagonal is √2 times the side length.
