Two sides are 3x longer than the shortest side. So, set up your problem like this.
X = unknown length in centimeters
3X = length of two longer sides
1X = length of short side
3x + 3x + 1x = 49
7x = 49
x = 7
So, two longer sides are 21 centimeters each and the short side is 7 centimeters.
21+21+7 = 49
29+18=47 17-8=9+47=56÷8=7 so its 7
30.8
you take 25^2 + 18^2 and find the square root of that which is 30.8 for this problem.
please give me brainliest :)
Let's simplify step-by-step.
2/5(d−10)−2/3(d+6)
Distribute:
= (2/5)(d)+(2/5)(−10)+ −2/3d+ −4
= 2/5d+−4+ −2/3d+ −4
Combine Like Terms:
= 2/5d+−4+ −2/3d+ −4
= −4/15d+−8
And your answer is...
= −4/15d+−8
plz mark me as brainliest if this helped :)
