Answer:
f(3) = 19
Step-by-step explanation:
Step 1: Define
f(x) = 2x² + 1
x = 3
Step 2: Substitute and Evaluate
f(3) = 2(3)² + 1
f(3) = 2(9) + 1
f(3) = 18 + 1
f(3) = 19
answer: 4s+4
(s+12)+(3s-8) distrubute --> s+12+3s-8
comibine like terms 4s+4
hopfully this helped :)
<em>Hello!</em>

We can say that: x = 127°
The sum of the hexagon's internal angles is 720 °. So, just solve an equation:
- 112 + 133 + 128 + 100 + 120 + x = 720
- 593 + x = 720
- x = 720 - 593
- x = 127°
So, x = 127°.

Answer:
The resultant expression would be 22 - 12x
Step-by-step explanation:
Let x be the unknown number,
Six plus four times a number = 6 + 4x
Four times four minus four times the number number = 4(4 - 4x)
Thus, Six plus four times the number plus four times four minus four times the number number = 6 + 4x + 4(4 - 4x)
Using distributive property,
6 + 4x + 16 - 16x
Combining like terms,
22 - 12x
