Answer:
x = 85
Step-by-step explanation:
The Pythagorean theorem is a property that is specific to right triangles, or triangles with a right angle. The Pythagorean theorem states the following,

Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or side opposite the right angle.
Substitute in the given values and solve,

I’m just guessing but since 13/4=3.25 that means that the triangle dialated by 3.25 so you multiply 8 by 3.25 and X might be 26
Answer:
2/5
Step-by-step explanation:
Answer:
See explanation
Step-by-step explanation:
A. Given the equation

Using the subtraction property of equality (subtracting 5 from both sides of equation), we'll get an equivalent equation

B. Given the equation

Using the addtion property of equality (adding 4 to both sides of equation), we'll get an equivalent equation

C. Given the equation

Using the division property of equality (dividing both sides of equation by 2), we'll get an equivalent equation

D. Given the equation

Using the multiplication property of equality (multiplying both sides of equation by 2), we'll get an equivalent equation

Legit way is vertex form
easy way is this
x value of vertex in form
f(x)=ax^2+bx+c is -b/2a
the y value is f(x value of vertex)
so
p(x)=-0.5x^2+40x-300
x value of vertex is -40/(2*-0.5)=-40/-1=40
