Answer:
11
Step-by-step explanation:
4, 9, 16, 25, 36, 49, 64, 81, 100, 121
So, what we're doing here is solving for x. We must isolate x to find it's value.
Here's how:
17 = 12(x + 2) + 2x
First, we'll distribute the 12
17 = 12*x + 12*2 + 2x
17 = 12x + 24 + 2x
Combine like terms
17 = 14x + 24
Then, we'll subtract 24 from both sides.
17 - 24 = 14x + 24 - 24
-7 = 14x
Then, to isolate x, we'll divide both sides by 14
-7/14 = x
x = -1/2
HIJ= 128 degrees
Explanation:
127x - 1 = 100 + 25x + 1
127x - 1 = 101 + 25x
-25x -25x
102x - 1 = 101
+1 +1
102x = 102
/102 /102
x = 1
2 - 4x⁹ + 3x³ - (7x + x³ - 6 + 12x⁴)
= 2 - 4x⁹ + 3x³ - 7x - x³ + 6 - 12x⁴
= (2 + 6) + (-4x⁹) + (3x³ - x³) + (-7x) + (-12x⁴) <em>grouped like terms</em>
= 8 - 4x⁹ +2x³ -7x -12x⁴ <em>added like terms</em>
= - 4x⁹ - 12x⁴ + 2x³ - 7x + 8 <em>standard form</em>
