Answer:
80
Step-by-step explanation:
The answer is B. (2x + 5)(x + 1)You could answer this by expanding each answer until you found one that matched 2x^2 + 7x + 5, but I will only show how the answer expands:
2x × x = 2x^2
5 × x = 5x
2x × 1 = 2x
5 × 1 = 5
So in total those brackets expand to 2x^2 + 7x + 5. I hope this helps!
Answer:111650
Step-by-step explanation:i think its right
Let the width = x
=>length = 2x-1
91= x(2x-1)=2x^2-x
2x^2-x-91=0
=(2x+13)(x-7)
=> x=-13/2=> no
=>x= 7 cm
17+(10X)= 21+(5x) is the equation
17 +(10x1)= 21+(5x1)
17+10=21+5
27=27
So your answer is it takes 1 mile per day
Hope its right lol
