Make the denominator the same, so multiple 3/10 by 2, which produces 6/20. Take 6/20 and subtract 7/20 because adding a negative number is the same as subtracting a positive number. the Answer is -1/20.
Ok i can help you solve this problem do you know the formula for quadratic equations
B. 21.39 because I said so and I did all the calculations and apparently I need more than 20 words but there is your answer enjoy
How much bigger is B than A , so Side length B- A = (-4x+18) - (2x-7) = -6x+25
So perimeter = 4x length = 4x(-6x+25) = -24x+100 = 100-24x
How much bigger? 100-24X
__Brainliest if i helped!
Answer:
Take 
Step-by-step explanation:
To begin notice that
If we chose the following delta
that solves our problem !
