Answer:
2b + 88 = 180
Step-by-step explanation:
Hope this helps
Answer:
1) Distance=Speed*time
90=(x+1)*(x)+(2x+5)(x-1)
90=x^2+x+2x^2-2x+5x-5
3x^2+4x-95=0
2) 3x^2+4x-95=0. Using quadratic formula, we get
x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.
3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours
Answer:
the graph has a minimum
Step-by-step explanation:
the minimum is -9
Answer:
The answer is 9.
Step-by-step explanation:
The degree of a monomial is defined as the sum of all the exponents of the variables, including the implicit exponents of 1 for the variables which appear without exponent.
<u>In this case, we will add 2, 6, and 1.</u>
2 + 6 + 1 = 9
