Answer:
7.5 hours (7 hours and 30 minutes)
Step-by-step explanation:
ok Let's start with 64km/h.
1.6 km=1 mile,
64÷1.6=40miles
so 64km/h changes into 40miles/hour.
Zebras's round trip =300miles,
300/40=7.5
so answer is 7.5 hours.
The LCM for 4 and 9 is 36
Answer:
To get the answer you need to add these together to find the total number of quarts she made.
8+5+5= 18 quarts of soup.
If everyone gets one cup, then 18 people are able to get soup.
The answer is 18 guests.
Step-by-step explanation:
Hope this helps!
Answer:
The answer is letter A.
(8x³ + 2x² - 7x + 2) ÷ (2x - 1)
8x³ + 2x² - 7x + 2 ÷ 2x - 1
(2x-1)(4x²+3x-2)÷2x-1
cancel 2x-1 so that the answer is 4x²+3x-2.
Answer:

Step-by-step explanation:
Biquadratic Equation
It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results
Our equation is

If we call
, our equation becomes a second-degree equation

Dividing by -3

Factoring

It leads to these solutions

Taking back the change of variable, we have for the first solution

Now for the second solution, we get imaginary (complex) values

Summarizing, the four solutions for x are
