Answer:
17x^2 -22x -2
Step-by-step explanation:
- 5x^2 +6x -2 +4x (3x-7)
- 5x^2 +6x -2 +12x^2 -28x
- 17x^2 +6x -2 -28x
- Answer: 17x^2 -22x -2
Just so you know when I put (^) the number after it is a exponent.
The one that looks like a V. It passes the vertical line test!
Answer:
The mathematical expression is false
Step-by-step explanation:
* Lets use the figure to answer the question
- There are four triangles in the figure
- Δ ROB and Δ PTA appear congruent because:
# The side RO appears equal the side PT
∴ RO ≅ PT
# The side OB appears equal the side TA
∴ OB ≅ TA
# The side RB appears equal the side PA
∴ RB ≅ PA ⇒ SSS
∴ Δ ROB ≅ Δ PTA
- Δ DEF and Δ YXW appear congruent because:
# The side DE appears equal the side YX
∴ DE ≅ YX
# The side EF appears equal the side XW
∴ EF ≅ XW
# The side DF appears equal the side YW
∴ DF ≅ YW
∴ Δ DEF ≅ Δ YXW ⇒ SSS
- Δ ROB and Δ DEF have different shapes and sizes
∵ Δ ROB not appear congruent to Δ DEF
∴ Δ ROB ≠ Δ DEF
∴ The mathematical expression is false
This question is complicated. But, based on the words, I would say that doubles is the key word. First we have to figure out how far it is between 11 and 2. Now we are going to turn 2 into a 2 digit number, since it is after 12 then we are going to add 12 to this number. 12+2=14. So now we are going to subtract 11 from 14. Leaving us with 3.
Now we know that there are 3 meters at 2, and it doubles every hour.
So we are going to take the square root of 3.
So that means that it was at 1.732050808 at 1 pm.
Now we are going to take the square root of that number.
Which means that at noon it was at 1.316074013.
And finally take the square root of that number.
So now we know that at 11 am it was at 1.14720269 meters.
I hope that helps, if you need any further help on this or any other problems just ask.
It would be answer A because answer A has the same slope as the equation in the question, none of the other answers have the same slope as 7/6. there is -7/6, but all that means is that the equation is negative. we need a positive equation.
