Omg! fellow k12 student:)
Answer:
9x-3
Step-by-step explanation:
To do this, we can make an equation and add like terms.
The equation is 2x+3x-1+4x-2=p. P stands for perimeter.
Now, simplify. Add like terms.
9x-1-2=p
9x-3=p
9x-3
The answer is D. 9x-3
Hope this helps!
Answer:
70
Step-by-step explanation:
- for the value of difference to be largest, the minuend should be maximum(most possibly) and the subtrahend should be minimum
[in A-B=X, A is minuend and B is subtrahend ]
- so, $a.b should be maximum. as there is a condition that 4 digits should be distinct, the product will be maximum if we choose 2 maximum valued numbers from the given numbers. so, one of them should be 9 and the other should be 8.
therefore, $a.b=9*8=72
- as mentioned above, c.d$ should be minimum. this will be possible only when we choose 2 minimum valued numbers from the given numbers. so, one of them should be 1 and the other should be 2.
therefore, c.d$ = 1*2 = 2
- hence, the difference = 72-2 = 70
- thus, the largest possible value of the difference $a.b - c.d$ = 70
Answer:
x= 5/4 this is correct answer hope it helps
