The answer for A would be 8.5 because if you use a^2+b^2=c^2 you would have 12^2 which equals 144 and you would divide that by two to get 72 and then take the square root to find the side length
The answer for be would be 45 because the sum of all angles in a triangle is 180 and you already know one is 90 and 180-90=90 and because this is an isosceles triangle you know the two bottom angles are equal so 90/2=45 <span />
Answer:
y=2x-5
Step-by-step explanation:

so the solution is not really a single number but a range, depending on how q is defined. I am assuming q is defined in domain of Real numbers, and then the solution to the inequality will be "all real numbers larger or equal to 4.7"
Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
