Answer:3x+6=2x+21 base angle of isosceles triangle
3x-2x=21-6
X=15
<J=3×15+6=51
<k=2×15+21=51
,<I=180-51-51=78
Step-by-step explanation:
Answer:
100?
Step-by-step explanation:
Yan po sagot ko e natama naman kami
identity used is
x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).
then use
(x+y+z)² = x²+y²+z²+2(xy+yz+xz)
225= 83 + 2(xy+yz+xz)
xy+yz+xz = (225-83)/2
xy+yz+xz= 142/2
xy+yz+xz= 71
ok
now use identity
x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).
now
x³ + y³+ z³– 3xyz = 15 (83 – xy – yz – zx).
= 15[83 - (71)]
= 15×12
=180

Answer:</h2><h2>The answer for the expression is 31</h2>
Step-by-step explanation:
The given expression is -4 + 5 + x + 4 = 36
To find the value of x, solve the given expression
Add the terms in the left hand side and compare with the right hand side to solve for "x"
-4 + 5 + x + 4 = 36
1 + x + 4 = 36
5 + x = 36
x = 36 - 5
x = 31
When any number/base is raised to the power of zero, it will always equal 1.
