Hey there!!!
Equation given :
p ( x ) = 3x² + 4x + 5
Find p ( 2x )
In order to solve this, we will have to substitute the value 2x instead of x
Hence,
... p ( 2x ) = 3 ( 2x )² + 4 ( 2x ) + 5
... p ( 2x ) = 3 ( 8x² ) + 8x + 5
... p ( 2x ) = 24x² + 8x + 5
As we know I ( x ) = p ( 2x )
The value of I(x) = 24x² + 8x + 5
Hope my answer helps!
Answer:
x=13
Step-by-step explanation:
1. divide both sides by 3
2. simplify: 4x-7=45
3. add 7 to both sides
4. 4x=52
5. divide both sides by 4
6. x=13
Answer: 04
Explanation: We are given 3-2x=-5. We would subtract 3 from both sides. The equation would then look like this after subtraction from both sides: -2x=-8. We would then divide -2 by both sides so we can isolate the variable. The equation would look like this x=4.
3-2x=-5
-2x=-8
x=4
70,000 is ten times as much as 7,000. This is because 7,000 times 10 equals 70,000. I got this answer by dividing 70,000 by 10.
