A*a + b*b = c*c
9*9 + 12*12 = c*c
81 + 144 = c*c
225 = c*c
✓225 = 15
c = 15
The hypotenuse is 15.
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
x=10,−1
Answer:
yes it is safe
Step-by-step explanation:
so if you d base times hight you will get 27 witch is the degrees of witch the triangle it creates
Hi there! :)

m(x) = 4x + 15
Find the value of "x" that would satisfy m(x) = 7:
4x + 15 = 7
Subtract 15 from both sides:
4x = -8
Divide both sides by 4:
x = -2.
