X is less than 5.
Because the circle is not closed, there’s no equal to.
Because it’s going to the left, it’s less.
The mean of 5 and 15 is 10. (5+15= 20 20/2=10)
Simplifying
3x2 + -5 = 70
Reorder the terms:
-5 + 3x2 = 70
Solving
-5 + 3x2 = 70
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + 3x2 = 70 + 5
Combine like terms: -5 + 5 = 0
0 + 3x2 = 70 + 5
3x2 = 70 + 5
Combine like terms: 70 + 5 = 75
3x2 = 75
Divide each side by '3'.
x2 = 25
Simplifying
x2 = 25
Take the square root of each side:
x = {-5, 5} and that’s it.
Answer:
Side lengths of 12,8,8
Step-by-step explanation:
In an isosceles triangle the base is different from the other 2 sides which are the same so
28=12+2x (x being the side of the repeat sides)
14=6+x (divide both sides by 2)
8=x (subtract 6 from both sides) so
Side lengths of 12,8,8
Answer:
C.
Step-by-step explanation: im pretty sure because if you look at Ed its 5 and then if you add the same sides twice its 10 hopefully im right
