Find the missing length of the triangle.

12 =c

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

7.2 ^2 + 9.6 ^2 = c^2

51.84+92.16= c^2

144 = c^2

Taking the square root of each side

sqrt(144) = sqrt(c^2)

12 =c

Let's find the hypotenuse.

7.2^2 + 9.6^2

51.84 + 92.16 = 144

√144(square root of 144) = 12, c = 12

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
