Which are the solutions of he quadratic equation ? x2 = 9x + 6
dedylja [7]
Put everything on the same side of the equals sign and set it equal to zero so you can factor it.  x^{2} -9x-6=0.  In order to factor that you have no choice really but to put it into the quadratic formula.  When you do that you find that your zeros are x = 9.623475383 and -.623475383

-10=3(2m+5)+5 whats the answer
pshichka [43]

Answer:

m=5

Step-by-step explanation:

multiply 3 with the numbers in the parentheses (2m + 5) when you have 6m + 15 you will plug it into -10=6m+15+5 add your commons which will be 15 + 5 which will be 20 so the equation will be -10=6m+20, now cross your 6m with your -10 which will be -10 + 6m = 20, now cross over your -10 with 20, now your equation will be 6m=20 + 10 so now you will get 6m = 30 now divide both sides by 6 and m=5

What is the length of the hypotenuse? If necessary, round to the nearest tenth.
Sauron [17]

Answer:

Here we need to use the Pythagorean Theorem. Which is: a^2 + b^2 = c^2

a^2 + b^2 = c^2

3.2^2 + 5.7^2 = c^2

10.24 + 32.49 = c^2

42.73 = c^2
