Answer: The Numbers are 15 and 39
Step-by-step explanation: 2(15) + 9 = 39
I haven’t taken this since for a while so my memory’s a bit foggy but I’m pretty sure it’s B since it intersects at (0,0) so there wont be any other solution. I hope that helps (:
Answer:
x=7
Step-by-step explanation:
8x +3 = 59
8x= 56
/8
x = 7
AB = 30 in and BC = 50 in.
We use Pythagorean theorem to solve this. Since AN is an altitude, this means that it is perpendicular to BC. This means BN and AN are the legs of one right triangle, with AB being the hypotenuse:
18²+24² = AB²
324 + 576 = AB²
900 = AB²
Take the square root of both sides:
√900 = √AB²
30 = AB
NC and AN form the legs of the other right triangle, with AC being the hypotenuse:
24²+NC² = 40²
576 + NC² = 1600
Subtract 576 from both sides:
576 + NC² - 576 = 1600 - 576
NC² = 1024
Take the square root of both sides:
√NC² = √1024
NC = 32
BC = BN + NC = 18 + 32 = 50
