Answer:
46.4 & 11.6
Step-by-step explanation:
I just did some guess and check, but 46.4/11.6 = 4 and 46.4+11.6 = 58

I think
Answer:
X=0
Step-by-step explanation:
Frst we want to check is it symmetry function?
F(-x)=f(x)?
We know that f(x)=x^2+0x-4=x^2-4.
What about f(-x)? F(-x)=(-x)^2-4=x^2-4, so we can conclud that f(-x)=f(x), the summetry!
Intesections with x is in the -2 and 2, so the middle is x=0.
Answer:
7 feet and 24 feet
Step-by-step explanation:
In the right triangle, the hypotenuse is 25 feet long. The area of this triangle is 84 square feet.
Let x feet and y feet be the lengths of triangle's legs.
By the Pythagorean theorem,

The area of the right triangle is half the product of its legs, thus

Solve the system of two equations:

From the second equation:

Substitute it into the first equation:

The length of the leg cannot be negative, so
